      public class SectionStack
      extends VLayout
      implements HasSectionHeaderClickHandlers

  A container that manages a list of sections of widgets, each with a header. Sometimes called an "Accordion".

  SectionStack can be configured so that only one section is visible at a time (similar to MS Outlook's left-hand Nav), or to allow multiple sections to be visible and share the available space.

                                     throws java.lang.IllegalStateException

      Widget to use for section headers.

      Must be a subclass of either `ImgSectionHeader` or `SectionHeader`. The default class used depends on the skin; `SectionHeader` is the simpler and lighter-weight class and uses CSS styling rather than image-based styling, and is recommended for most use cases.

      If you create a custom section header class in Java, enable `Reflection` to allow it to be used.

      Alternatively, you can use the SmartClient class system to create a simple SmartClient subclass of either SectionHeader or ImgSectionHeader for use with this API - see the `Skinning Guide` for details.

      If you override event handlers on your custom SectionHeader or radically change it's structure such that the default event handling no longer works, you can call `sectionHeaderClick()` to replicate the built-in expand/collapse handling for clicking a section header.

      Note : This is an advanced setting

      Parameters:
        `sectionHeaderClass` - New sectionHeaderClass value. Default value is "SectionHeader"
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created

    - #### getSectionHeaderClass

          public java.lang.String getSectionHeaderClass()

    - #### setShowExpandControls

          public void setShowExpandControls(java.lang.Boolean showExpandControls)

    - #### getShowExpandControls

          public java.lang.Boolean getShowExpandControls()

    - #### setVisibilityMode

          public void setVisibilityMode(VisibilityMode visibilityMode)

      Set arbitrary properties for a particular section in this SectionStack. Properties will be applied to the sectionHeader for the section.

      Note that where APIs exist to explicitly manipulate section properties these should be used in preference to this method. For example, to add or remove items in a section use `addItem()` or `removeItem()`. To change the title of a section, use `setSectionTitle()`.

      Also note that to modify properties of items within a section, call the appropriate setter methods directly on the item you want to modify.

        `section` - ID or index of the section to modify
        `properties` - properties to apply to the section.

    - #### setDefaultProperties

          public static void setDefaultProperties(SectionStack sectionStackProperties)

      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 set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. 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:
        `sectionStackProperties` - properties that should be used as new defaults when instances of this class are created
      See Also:
        `SGWTProperties`
