    - #### setAddUnknownValues

          public void setAddUnknownValues(java.lang.Boolean addUnknownValues)

      If this item's value is set (via `SelectItem.setValue()` or similar) to a value which is not present in the `com.smartgwt.client.types.ValueMap`, should the value be rejected.

      If set to `false` the setValue() call will have no effect if the value is not a valid option.

      If set to `true` the item's value will be update to the new value, and the value will be added to the set of options displayed in the pick-list until the next call to `SelectItem.setValueMap()` or `SelectItem.setValue()`.

      Exception: If the value is set to `null` but there is no null entry in the valueMap for this item, setting `addUnknownValues` to true will not cause a null option to show up at the top of the select item pickList. Whether an empty option is shown in the pickList is governed by `allowEmptyValue` instead.

      Note that this property has no effect if the selectItem has a specified `optionDataSource`. If `SelectItem.setValue()` is called on a databound SelectItem and the new value does not match any loaded options, the value will be accepted, but not added to the options displayed in the pickList. Also note that if a `displayField` exists, a fetch will be performed in an attempt to retrieve a valid display value, as described under `fetchMissingValues`. If specified the `loadingDisplayValue` will be displayed while the fetch is in progress, and then the real value (mapped to a display field value if a matching record was found) will be displayed when the fetch completes.

      Note : This is an advanced setting

      Parameters:
        `addUnknownValues` - Default value is true
      See Also:
        Dependent Selects Example

    - #### getAddUnknownValues

          public java.lang.Boolean getAddUnknownValues()

      If this item's value is set (via `SelectItem.setValue()` or similar) to a value which is not present in the `com.smartgwt.client.types.ValueMap`, should the value be rejected.

      If set to `false` the setValue() call will have no effect if the value is not a valid option.

      If set to `true` the item's value will be update to the new value, and the value will be added to the set of options displayed in the pick-list until the next call to `SelectItem.setValueMap()` or `SelectItem.setValue()`.

    - #### setAllowEmptyValue

          public void setAllowEmptyValue(java.lang.Boolean allowEmptyValue)

      If set to true, always show an empty option in this item's pickList, allowing the user to clear the value (even if there is no empty entry in the valueMap for the item).

      The empty value will be displayed with the `emptyDisplayValue`.

      With a `databound selectItem`, enabling `allowEmptyValue` disables data paging by default - all data matching the current criteria will be requested. However, enabling `separateSpecialValues` allows data paging to be used if required.

      See also `specialValues` as a way of providing several different special values in addition to an empty value, such as "Invalid". Note that setting `specialValues` disables the use of `allowEmptyValue` - see details of how to have an empty value while using `specialValues` in in `the `specialValues` documentation`.

      Parameters:
        `allowEmptyValue` - Default value is false

    - #### getAllowEmptyValue

          public java.lang.Boolean getAllowEmptyValue()

      If set to true, always show an empty option in this item's pickList, allowing the user to clear the value (even if there is no empty entry in the valueMap for the item).

      The empty value will be displayed with the `emptyDisplayValue`.

      With a `databound selectItem`, enabling `allowEmptyValue` disables data paging by default - all data matching the current criteria will be requested. However, enabling `separateSpecialValues` allows data paging to be used if required.

      Returns:
        Boolean

    - #### setAutoFetchData

          public void setAutoFetchData(java.lang.Boolean autoFetchData)

      If this select item retrieves its options from a `dataSource`, should options be fetched from the server when the item is first drawn, or should this fetch be delayed until the user opens the pickList.

      The default is true in order to allow the user to select a value via keyboard input while keyboard focus is on the SelectItem but the pickList has not actually been shown.

      Note : This is an advanced setting

      Parameters:
        `autoFetchData` - Default value is true

    - #### getAutoFetchData

          public java.lang.Boolean getAutoFetchData()

      If this select item retrieves its options from a `dataSource`, should options be fetched from the server when the item is first drawn, or should this fetch be delayed until the user opens the pickList.

      The default is true in order to allow the user to select a value via keyboard input while keyboard focus is on the SelectItem but the pickList has not actually been shown.

      Returns:
        Boolean

    - #### setCachePickListResults

          public void setCachePickListResults(java.lang.Boolean cachePickListResults)

      For databound pickLists (see optionDataSource), by default Smart GWT will cache and re-use datasets shown by pickLists in an LRU (least recently used) caching pattern.

      Setting this flag to false avoids this caching for situations where it is too aggressive.

      Parameters:
        `cachePickListResults` - Default value is true

    - #### getCachePickListResults

          public java.lang.Boolean getCachePickListResults()

      For databound pickLists (see optionDataSource), by default Smart GWT will cache and re-use datasets shown by pickLists in an LRU (least recently used) caching pattern.

      Setting this flag to false avoids this caching for situations where it is too aggressive.

      Returns:
        Boolean

    - #### setCanSelectText

          public void setCanSelectText(boolean canSelectText)

      By default SelectItems do not allow users to select the text of the selected value.
      Overrides:
        `setCanSelectText` in class `FormItem`
      Parameters:
        `canSelectText` - Default value is false

    - #### getCanSelectText

          public boolean getCanSelectText()

      By default SelectItems do not allow users to select the text of the selected value.
      Overrides:
        `getCanSelectText` in class `FormItem`
      Returns:
        boolean

    - #### setControlStyle

          public void setControlStyle(java.lang.String controlStyle)

      Base CSS class name for a form item's control box (surrounds text box and picker).

      NOTE: See the `CompoundFormItem_skinning` discussion for special skinning considerations.

      Overrides:
        `setControlStyle` in class `FormItem`
      Parameters:
        `controlStyle` - See `FormItemBaseStyle` . Default value is "selectItemControl", [IRA]
      See Also:
        `FormItem.setCellStyle(java.lang.String)`, `Appearance overview and related methods`

    - #### getControlStyle

          public java.lang.String getControlStyle()

      Base CSS class name for a form item's control box (surrounds text box and picker).

      NOTE: See the `CompoundFormItem_skinning` discussion for special skinning considerations.

      Overrides:
        `getControlStyle` in class `FormItem`
      Returns:
        See `FormItemBaseStyle`
      See Also:
        `FormItem.getCellStyle()`, `Appearance overview and related methods`

    - #### setDefaultToFirstOption

          public void setDefaultToFirstOption(java.lang.Boolean defaultToFirstOption)

      Select the first option as the default value for this SelectItem.

      If options are derived from a dataSource, the first value returned by the server will be used, otherwise the first value in the valueMap. Note that setting this property to true will trigger a fetch at soon as the form is created, because the form will try to establish a default value at that time.

      If enabled, this setting overrides `defaultValue` and `SelectItem.defaultDynamicValue()`.

      Parameters:
        `defaultToFirstOption` - Default value is false

    - #### getDefaultToFirstOption

          public java.lang.Boolean getDefaultToFirstOption()

      Select the first option as the default value for this SelectItem.

      If options are derived from a dataSource, the first value returned by the server will be used, otherwise the first value in the valueMap. Note that setting this property to true will trigger a fetch at soon as the form is created, because the form will try to establish a default value at that time.

      If enabled, this setting overrides `defaultValue` and `SelectItem.defaultDynamicValue()`.

      Returns:
        Boolean

    - #### setDefaultValue

          public void setDefaultValue(java.lang.Boolean defaultValue)

      Static default value for this SelectItem. To default to the first option use `defaultToFirstOption` instead.
      Overrides:
        `setDefaultValue` in class `FormItem`
      Parameters:
        `defaultValue` - Default value is null

    - #### getDefaultValue

          public java.lang.Boolean getDefaultValue()

      Static default value for this SelectItem. To default to the first option use `defaultToFirstOption` instead.
      Returns:
        Boolean

    - #### setDisplayField

          public void setDisplayField(java.lang.String displayField)

      Specifies an alternative field from which display values should be retrieved for this item.

      The display field can be either another field value in the same record or a field that must be retrieved from a related `optionDataSource`. For fields with an `optionDataSource`, developers may explicitly specify `foreignDisplayField`. If that property is unset, the standard `displayField` value will be used by default.

      If this item is not databound (`optionDataSource` is unset), or bound to the same dataSource as the form as a whole, this item will call `form.getValue()` the form named after is implemented by picking up the value of the specified field from the Form's values object.

      Otherwise this item will attempt to map its underlying value to a display value by retrieving a record from the `optionDataSource` where the `valueField` matches this item's value, and displaying the `displayField` value from that record. (Even if specified, the field may not be used if it does not match any fields present in the optionDataSource - see `SelectItem.getDisplayFieldName()` for details). Note that if `optionDataSource` is set and no valid display field is specified (via `foreignDisplayField`, or this property), `FormItem.getDisplayFieldName()` will return the dataSource title field by default.

      This essentially enables the specified `optionDataSource` to be used as a server based `valueMap`.

      Note that, when entering free-form search values, items will select the first match in their valueMap or pickList. This means that it can't be guaranteed that a given search-value will return the same valueField value if there are duplicate displayField values in the available options.

      Specified by:
        `setDisplayField` in interface `PickList`
      Overrides:
        `setDisplayField` in class `FormItem`
      Parameters:
        `displayField` - Default value is null
      See Also:
        `FormItem.getDisplayFieldName()`, `FormItem.invalidateDisplayValueCache()`, List - Related Records Example

    - #### getDisplayField

          public java.lang.String getDisplayField()

      Specifies an alternative field from which display values should be retrieved for this item.

      The display field can be either another field value in the same record or a field that must be retrieved from a related `optionDataSource`. For fields with an `optionDataSource`, developers may explicitly specify `foreignDisplayField`. If that property is unset, the standard `displayField` value will be used by default.

      If this item is not databound (`optionDataSource` is unset), or bound to the same dataSource as the form as a whole, this item will call `form.getValue()` the form named after is implemented by picking up the value of the specified field from the Form's values object.

      Otherwise this item will attempt to map its underlying value to a display value by retrieving a record from the `optionDataSource` where the `valueField` matches this item's value, and displaying the `displayField` value from that record. (Even if specified, the field may not be used if it does not match any fields present in the optionDataSource - see `SelectItem.getDisplayFieldName()` for details). Note that if `optionDataSource` is set and no valid display field is specified (via `foreignDisplayField`, or this property), `FormItem.getDisplayFieldName()` will return the dataSource title field by default.

      This essentially enables the specified `optionDataSource` to be used as a server based `valueMap`.

      Note that, when entering free-form search values, items will select the first match in their valueMap or pickList. This means that it can't be guaranteed that a given search-value will return the same valueField value if there are duplicate displayField values in the available options.

      Specified by:
        `getDisplayField` in interface `PickList`
      Overrides:
        `getDisplayField` in class `FormItem`
      Returns:
        Returns the `displayField` for this item.

        Behavior varies based on the configuration of this item, as follows:

        - If this item has an `optionDataSource` and an explicit `foreignDisplayField` is specified, this will be returned.
        - Otherwise if an explicit `displayField` is specified it will be returned by default. If the `displayField` was specified on the underlying dataSource field, and no matching field is present in the `optionDataSource` for the item, we avoid returning the specified displayField value and instead return the title field of the option DataSource. We do this to avoid confusion for the case where the displayField is intended as a display-field value for showing another field value within the same record in the underlying dataSource only.
        - If no explicit foreignDisplay or displayField specification was found, and the `valueField` for this item is hidden in the `optionDataSource`, this method will return the title field for the `optionDataSource`.

      Overrides:
        `getEditProxyConstructor` in class `FormItem`
      Returns:
        See `SCClassName`

    - #### setEmptyDisplayValue

          public void setEmptyDisplayValue(java.lang.String emptyDisplayValue)

      Text to display when this form item has a null or undefined value.

      If the formItem has a databound pickList, and its `displayField` or `valueField` (if the former isn't set) has an undefined `emptyCellValue` setting, that field's `emptyCellValue` will automatically be set to the `emptyDisplayValue`.

      Overrides:
        `setEmptyDisplayValue` in class `FormItem`
      Parameters:
        `emptyDisplayValue` - See `HTMLString` . Default value is "&nbsp;"

    - #### getEmptyDisplayValue

          public java.lang.String getEmptyDisplayValue()

      Text to display when this form item has a null or undefined value.

      If the formItem has a databound pickList, and its `displayField` or `valueField` (if the former isn't set) has an undefined `emptyCellValue` setting, that field's `emptyCellValue` will automatically be set to the `emptyDisplayValue`.

      Overrides:
        `getEmptyDisplayValue` in class `FormItem`
      Returns:
        See `HTMLString`

    - #### setEmptyPickListMessage

          public void setEmptyPickListMessage(java.lang.String emptyPickListMessage)

      Empty message to display in the selectItem if hideEmptyPickList is `false`.

      Note : This is an advanced setting

      Specified by:
        `setEmptyPickListMessage` in interface `PickList`
      Parameters:
        `emptyPickListMessage` - Default value is "No items to show"

    - #### getEmptyPickListMessage

          public java.lang.String getEmptyPickListMessage()

      Empty message to display in the selectItem if hideEmptyPickList is `false`.
      Specified by:
        `getEmptyPickListMessage` in interface `PickList`
      Returns:
        String

    - #### setEscapeHTML

          public void setEscapeHTML(java.lang.Boolean escapeHTML)

      By default HTML values in a selectItem will be interpreted by the browser. Setting this flag to true will causes HTML characters to be escaped, meaning the raw value of the field (for example `"<b>AAA</b>"`) is displayed to the user rather than the interpreted HTML (for example `"AAA"`)
      Parameters:
        `escapeHTML` - Default value is false
      See Also:
        `Appearance overview and related methods`

    - #### getEscapeHTML

          public java.lang.Boolean getEscapeHTML()

      By default HTML values in a selectItem will be interpreted by the browser. Setting this flag to true will causes HTML characters to be escaped, meaning the raw value of the field (for example `"<b>AAA</b>"`) is displayed to the user rather than the interpreted HTML (for example `"AAA"`)
      Returns:
        Boolean

        `Appearance overview and related methods`

    - #### setFetchDisplayedFieldsOnly

          public void setFetchDisplayedFieldsOnly(java.lang.Boolean fetchDisplayedFieldsOnly)

      If this item has a specified `optionDataSource` and this property is `true`, the list of fields used by this pickList will be passed to the datasource as `outputs`. If the datasource supports this feature the returned fields will be limited to this list. A custom datasource will need to add code to implement field limiting.

      This list of used fields consists of the values of `valueField`, `displayField` and `pickListFields`.

      NOTE: When enabled, `getSelectedRecord` will only include the fetched fields.

      Note : This is an advanced setting

      Parameters:
        `fetchDisplayedFieldsOnly` - Default value is null

    - #### getFetchDisplayedFieldsOnly

          public java.lang.Boolean getFetchDisplayedFieldsOnly()

      If this item has a specified `optionDataSource` and this property is `true`, the list of fields used by this pickList will be passed to the datasource as `outputs`. If the datasource supports this feature the returned fields will be limited to this list. A custom datasource will need to add code to implement field limiting.

      This list of used fields consists of the values of `valueField`, `displayField` and `pickListFields`.

      NOTE: When enabled, `getSelectedRecord` will only include the fetched fields.

      Returns:
        Boolean

    - #### setFilterLocally

          public void setFilterLocally(java.lang.Boolean filterLocally)

      If `filterLocally` is set for this item, and this item is showing options from a dataSource, fetch the entire set of options from the server, and use these values to map the item value to the appropriate display value. Also use `"local"` type filtering on drop down list of options.

      This means data will only be fetched once from the server, and then filtered on the client.

      Note - when this property is set to `false`, filtering will still be performed on the client if a complete set of data for some criteria has been cached by a fetch, and a subsequent fetch has more restrictive criteria. To explicitly disable client-side filtering set the `useClientFiltering` property to false.

      Note : This is an advanced setting

      Specified by:
        `setFilterLocally` in interface `PickList`
      Overrides:
        `setFilterLocally` in class `FormItem`

    - #### setIconPlacement

          public void setIconPlacement(PickListItemIconPlacement iconPlacement)

      For PickList items with `PickListItemIconPlacement` set such that the pickList does not render near-origin, should specified `icons` be rendered inline within the formItem itself, or within the `pickerNavigationBar`.

      May be overridden at the icon level via `iconPlacement`.

      For mobile browsing with limited available screen space, icons rendered in the navigation bar may be easier for the user to interact with.

      Parameters:
        `iconPlacement` - Default value is "both"

    - #### getIconPlacement

          public PickListItemIconPlacement getIconPlacement()

      For PickList items with `PickListItemIconPlacement` set such that the pickList does not render near-origin, should specified `icons` be rendered inline within the formItem itself, or within the `pickerNavigationBar`.

    - #### setMultiple

          public void setMultiple(java.lang.Boolean multiple)

      If true, multiple values may be selected.

      The SelectItem will either render as a drop-down allowing multiple selections, or a multi-row list of options similar to a small headerless `ListGrid`, based on the `MultipleAppearance` setting.

      The logical value of the formItem, as retrieved by `getValue()` and set via `setValue()`, is an Array of Strings reflecting the selected values.

      When this value is true, we disable doubleClick events by default, instead issuing two single clicks by forcibly setting `noDoubleClicks: true`. If you need to work with doubleClick events, you can disable this default behavior by explicitly setting formItem.pickListProperties.noDoubleClicks: false.

      Note: `multiple:true` SelectItems with multipleAppearance:"grid" do not currently support optionDataSource binding. You can get around this by calling `DataSource.fetchData()` directly and calling `dsResponse.data.getValueMap()` to obtain a valueMap.

      Parameters:
        `multiple` - Default value is false
      See Also:
        `Appearance overview and related methods`

    - #### setSpecialValues

          public void setSpecialValues(java.util.Map specialValues)

      A set of "special" values such as "All", "None" or "Invalid" that do not appear in the normal `com.smartgwt.client.types.ValueMap` or in the data returned by the `optionDataSource`.

      Like other uses of `com.smartgwt.client.types.ValueMap`, either a list of values or a mapping from stored to display value can be provided.

      These values can either be shown at the top of the list of values (in the order specified), or can be shown in a separate, non-scrolling region - the setting `separateSpecialValues` controls this. Note that data paging can only be used if `separateSpecialValues` is enabled.

      If `specialValues` are configured, `allowEmptyValue` is ignored - an empty value, if desired, must be included in the `specialValues`. To provide a `specialValue` which clears the value of the field, use the special constant emptyStoredValue.

      `specialValues` can also be used to take a value that does appear in the normal data and redundantly display it at the top of the list to make it more accessible. Note that in this case it is expected that the special value appears both at the top of the list and in it's normal position in the list, so this works best with `separateSpecialValues` mode enabled.

      Also, if an `optionDataSource` is used, `specialValues` that appear in the normal dataset will be updated by automatic `cache synchronization` (if the `displayField` is updated). However when using a distinct `valueField` and `displayField`, you are required to provide `specialValues` as a map (there is no support for `fetchMissingValues` automatically fetching appropriate display values).

      Note that specialValues are not supported in conjunction with `selectItem.multiple:true` or `MultiComboBoxItem`.

      Parameters:
        `specialValues` - Default value is null

    - #### getSpecialValues

          public java.util.Map getSpecialValues()

      A set of "special" values such as "All", "None" or "Invalid" that do not appear in the normal `com.smartgwt.client.types.ValueMap` or in the data returned by the `optionDataSource`.

    - #### getDisplayFieldName

          public java.lang.String getDisplayFieldName()

      Returns the `displayField` for this item.

      Behavior varies based on the configuration of this item, as follows:

      - If this item has an `optionDataSource` and an explicit `foreignDisplayField` is specified, this will be returned.
      - Otherwise if an explicit `displayField` is specified it will be returned by default. If the `displayField` was specified on the underlying dataSource field, and no matching field is present in the `optionDataSource` for the item, we avoid returning the specified displayField value and instead return the title field of the option DataSource. We do this to avoid confusion for the case where the displayField is intended as a display-field value for showing another field value within the same record in the underlying dataSource only.
      - If no explicit foreignDisplay or displayField specification was found, and the `valueField` for this item is hidden in the `optionDataSource`, this method will return the title field for the `optionDataSource`.
      Specified by:
        `getDisplayFieldName` in interface `PickList`
      Overrides:
        `getDisplayFieldName` in class `FormItem`
      Returns:

      Getter method to retrieve the `valueField` for this item. If unset, default behavior will return the `name` of this field.
      Specified by:
        `getValueFieldName` in interface `PickList`
      Overrides:
        `getValueFieldName` in class `FormItem`
      Returns:
        fieldName to use a "value field" in records from this items `optionDataSource`

    - #### showPicker

          public void showPicker()

      Method to show a picker for this item. By default this method is called if the user clicks on a `pickerIcon`. May also be called programmatically.

      Default implementation lazily creates and shows the `Picker Autochild`. May be overridden to implement some custom picker for this item.

      Overrides:
        `showPicker` in class `FormItem`

    - #### setDefaultProperties

          public static void setDefaultProperties(SelectItem selectItemProperties)

      Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

      Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

      Parameters:
        `selectItemProperties` - properties that should be used as new defaults when instances of this class are created

    - #### getPickListFilterCriteria

          protected Criteria getPickListFilterCriteria()

      Returns a set of filter criteria to be applied to the data displayed in the pickList when it is shown.
      If this is a databound item, the criteria will be passed as criteria to DataSource.fetchData(). Otherwise an equivalent client-side filter will be performed on the data returned by PickList.getClientPickListData().
      By default returns PickList.pickListCriteria if specified, otherwise an empty set of criteria so all records will be displayed. Note : this is an override point - if overridden this method will be called by the live form item during filtering. However it is recommended that developers use `setPickListFilterCriteriaFunction(FormItemCriteriaFunction)` to build custom criteria instead of overriding this method directly. This ensures that the custom filter criteria generating code will be called even if the form item was automatically generated based on a template passed to `ListGridField.setEditorType(com.smartgwt.client.widgets.form.fields.FormItem)`.
      Returns:
        criteria to be used for databound or local filtering

      Specifies the field by which this item should be initially sorted. Can be set to either a `'field name'` or the index of the field in the fields Array. Note that if `sortField` is initially specified as a number, it will be converted to a string (field name) after the item is initialized.

      To programmatically change sort field or direction after initialization, call ${isc.DocUtils.linkForRef('sort')}.

      Returns:
        Integer

    - #### setValueIconField

          public void setValueIconField(java.lang.String valueIconField)

      For Databound formItems, this property determines which column `valueIcons` should show up in for this formItem's pickList.
      If unset valueIcons show up in the `displayField` column if specified, otherwise the `valueField` column.
      In most cases only the `displayField` or `valueField` will be visible. This property is typically only required if custom `pickListFields` have been specified for this item.

      Note : This is an advanced setting

      Specified by:
        `setValueIconField` in interface `PickList`
      Parameters:
        `valueIconField` - valueIconField Default value is null

    - #### getValueIconField

          public java.lang.String getValueIconField()

      For Databound formItems, this property determines which column `valueIcons` should show up in for this formItem's pickList.
      If unset valueIcons show up in the `displayField` column if specified, otherwise the `valueField` column.
      In most cases only the `displayField` or `valueField` will be visible. This property is typically only required if custom `pickListFields` have been specified for this item.
      Specified by:
        `getValueIconField` in interface `PickList`
      Returns:
        String

    - #### setShowAllOptions

          public void setShowAllOptions(java.lang.Boolean showAllOptions)

      If true, even non-matching options will be shown, with configurable `separatorRows` in between. Not valid for `optionDataSource`.
      Specified by:
        `setShowAllOptions` in interface `PickList`
      Parameters:
        `showAllOptions` - showAllOptions Default value is null

    - #### getShowAllOptions

          public java.lang.Boolean getShowAllOptions()

      If true, even non-matching options will be shown, with configurable `separatorRows` in between. Not valid for `optionDataSource`.
      Specified by:
        `getShowAllOptions` in interface `PickList`
      Returns:
        Boolean

    - #### setPickListCriteria

          public void setPickListCriteria(DSRequest optionFilterContext)

      If this item has a specified `optionDataSource`, and this property is not null, this will be passed to the datasource as `RPCRequest` properties when performing the filter operation on the dataSource to obtain the set of options for the list.

      Note : This is an advanced setting

      Parameters:
        `optionFilterContext` - optionFilterContext Default value is null

    - #### setOptionDataSource

          public void setOptionDataSource(DataSource dataSource)

      If set, this FormItem will derive data to show in the PickList by fetching records from the specified `optionDataSource`. The fetched data will be used as a `valueMap` by extracting the `valueField` and `displayField` in the loaded records, to derive one valueMap entry per record loaded from the optionDataSource. Multiple fields from the fetched data may be shown in the pickList by setting `pickListFields`.

      The data will be retrieved via a "fetch" operation on the DataSource, passing the `pickListCriteria` (if set) as criteria, and passing `optionFilterContext` (if set) as DSRequest properties.

      The fetch will be triggered when the pickList is first shown, or, you can set `autoFetchData` to fetch when the FormItem is first drawn. You can also call `com.smartgwt.client.widgets.form.fields.PickList#fetchData` at any time to manually trigger a fetch.

      Data paging is automatically enabled if the optionDataSource supports it. As the pickList is scrolled by the user, requests for additional data will be automatically issued.

      For a pickList attached to a ComboBoxItem, new fetches are issued as the user types, with criteria set as described under `ComboBoxItem.getPickListFilterCriteria()`. If your dataSource is not capable of filtering results by search criteria (eg the dataSource is backed by an XML flat file), you can set `filterLocally` to have the entire dataset loaded up front and filtering performed in the browser. This disables data paging.

      Setting optionDataSource also enables the basic `optionDataSource` behaviors, eg, fetching individual display values before the pickList is shown.

      Note that if a normal, static `valueMap` is also specified for the field (either directly in the form item or as part of the field definition in the dataSource), it will be preferred to the data derived from the optionDataSource for whatever mappings are present.

      Note : This is an advanced setting

      Specified by:
        `setOptionDataSource` in interface `PickList`
      Overrides:
        `setOptionDataSource` in class `FormItem`

      Parameters:
        `defaultValues` - the defaultValues. Default value is null

    - #### setFetchDelay

          public void setFetchDelay(java.lang.Integer fetchDelay)

      Description copied from interface: `PickList`
      For a ComboBox or other pickList that accepts user-entered criteria, how many millseconds to wait after the last user keystroke before fetching data from the server. The default setting will initiate a fetch if the stops typing or pauses briefly.
      Specified by:
        `setFetchDelay` in interface `PickList`
      Parameters:
        `fetchDelay` - the fetch delay. defaults to 200ms

    - #### getFetchDelay

          public java.lang.Integer getFetchDelay()

      Description copied from interface: `PickList`
      For a ComboBox or other pickList that accepts user-entered criteria, how many millseconds to wait after the last user keystroke before fetching data from the server. The default setting will initiate a fetch if the stops typing or pauses briefly.
      Specified by:
        `getFetchDelay` in interface `PickList`
      Returns:
        the fetch delay

    - #### getValues

          public java.lang.String[] getValues()

      Returns the values of a SelectItem with multiple=true as an array of Strings.
      Returns:
        value of selection. If no values are selected, and empty array is returned

    - #### setValues

          public void setValues(java.lang.String... values)

      Set the values of a SelectItem with multiple=true.
      Parameters:
        `values` - the SelectItem values

    - #### isMultiple

          public java.lang.Boolean isMultiple()

      If true, multiple values may be selected.

      The SelectItem will either render as a drop-down allowing multiple selections, or a multi-row list of options similar to a small headerless `ListGrid`, based on the `MultipleAppearance` setting.

      The logical value of the formItem, as retrieved by `getValue()` and set via `setValue()`, is an Array of Strings reflecting the selected values.

      When this value is true, we disable doubleClick events by default, instead issuing two single clicks by forcibly setting `noDoubleClicks: true`. If you need to work with doubleClick events, you can disable this default behavior by explicitly setting formItem.pickListProperties.noDoubleClicks: false.

      Note: `multiple:true` SelectItems do not currently support optionDataSource binding. You can get around this by calling `DataSource.fetchData` directly and calling `dsResponse.data.getValueMap()` to obtain a valueMap.

      Returns:
        Boolean
      See Also:
        `Appearance overview and related methods`

    - #### filterClientPickListData

          public ListGridRecord[] filterClientPickListData()

      Description copied from interface: `PickList`
      Returns the data to display in the pick list.

      The default implementation applies the criteria returned by `#getPickListFilterCriteria` to the data returned by `PickList.getClientPickListData()`. A record passes the filter if it has a matching value for all fields in the criteria object. Matching is performed according to `textMatchStyle`.

      If `showAllOptions` is set, all values are shown, with matching values shown below a `separator`.

      Specified by:
        `filterClientPickListData` in interface `PickList`
      Returns:
        array of record objects to display in the pickList

    - #### getClientPickListData

          public ListGridRecord[] getClientPickListData()

      Description copied from interface: `PickList`
      Returns the set of data to be displayed in this item's PickList.

      This method will be called for non-databound form items implementing the PickList interface. The default implementation will derive data from the item's valueMap - can be overridden to allow a custom set of options to be displayed.

      Note that for PickLists that filter data based on user input `'ComboBox')`, this method should return the data before filtering.

      Specified by:
        `getClientPickListData` in interface `PickList`
      Returns:
        Array of record objects to be displayed in the pickList. Note that when a user picks a record from the list, the value of the field matching item.valueField will be picked. Also note that the fields to be displayed can be customized via item.pickListFields

    - #### getSelectedRecord

          public ListGridRecord getSelectedRecord()

      Returns the entire record object associated with the current value for this item (or null if no matching record exists in the PickList data). Most commonly used for databound pickListItems to retrieve the values of other fields in the record.
      Overrides:
        `getSelectedRecord` in class `FormItem`
      Returns:
        the selected record or null

    - #### setOptionFilterContext

          public void setOptionFilterContext(DSRequest dsRequestProperties)

      Description copied from interface: `PickList`
      If this item has a specified `optionDataSource`, and this property is not null, this will be passed to the datasource as `RPCRequest` properties when performing the fetch operation on the dataSource to obtain a data-value to display-value mapping

      Note : This is an advanced setting

      Specified by:

    - #### setPickListSort

          public void setPickListSort(SortSpecifier[] sortSpecifiers)

      This method sorts the pickList on one or more fields, creating the underlying JS object if needed. Pass in an array of SortSpecifiers to have the grid's data sorted by the fields in each specifier.property and in the directions specified. The grid can be sorted by any combination of fields, including fields specified in the fields array, whether visible or hidden, and `'unused fields from the underlying dataSource'`, if there is one. If multiple fields are sorted, those that are visible show a directional icon and a small `'sort-numeral'` indicating that field's index in the sort configuration.

      See `ListGrid.addSort(com.smartgwt.client.data.SortSpecifier)` and `com.smartgwt.client.widgets.grid.ListGrid#alterSort` APIs for information on making changes to the current sort configuration.

      Parameters:
