      public class SectionItem
      extends CanvasItem

  Header item for a collapsible section in a `DynamicForm`. Each `SectionItem` is associated with a number of other `item`s in the form, which will be shown or hidden as a group when the section is expanded or collapsed. Clicking on a `SectionItem` will expand or collapse the section.

  To make a form where only one section is expanded at a time, set `sectionVisibilityMode` to "mutex".

    `DynamicForm.getSectionVisibilityMode()`

Very advanced developers can use the following information to create custom header classes.

      Note : This is an advanced setting

      Parameters:
        `sectionHeaderClass` - . See `Classname`. Default value is "SectionHeader"

    - #### getSectionHeaderClass

          public java.lang.String getSectionHeaderClass()

      Name of the Canvas subclass to use as a header that labels the section and allows showing and hiding. The default class be skinned, or trivial subclasses created to allow different appearances for SectionItems in different forms. Very advanced developers can use the following information to create custom header classes.
      Returns:
        . See `Classname`

    - #### collapseSection

          public void collapseSection()

      Collapse a sectionItem, and hide all the items within the section (not including the header).

    - #### expandSection

          public void expandSection()

      Expands a section, showing all the items contained within the section.

    - #### isExpanded

          public java.lang.Boolean isExpanded()

      Returns a boolean indicating whether this SectionItem is expanded.
      Returns:
        true if the section is expanded false if not

    - #### setDefaultProperties

          public static void setDefaultProperties(SectionItem sectionItemProperties)

      Class level method to set the default properties of this class. If set, then all subsequent instances of this class will automatically have the default properties that were set when this method was called. 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 effect 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.

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

    - #### setItemIds

          public void setItemIds(java.lang.String... itemIds)

      IDs of the items that should be considered a member of this section.
      Parameters:
        `itemIds` - itemIds Default value is null
