      public class SectionStackSection
      extends RefDataClass

  Section descriptor used by a SectionStack to describe a section of items which are shown or hidden together along with their associated header.

  A `SectionStackSection` can't be modified once it's been added to a `SectionStack`, which creates its section header (by default a `SectionHeader`, but see `SectionStack.sectionHeaderClass`). After that, you must call the appropriate `SectionStack` method to modify a section property, or the section header getter method to get the updated property value. As a convenience, we route several `SectionStackSection` setter methods to the `SectionStack` for you after the `SectionStackSection` has been added to it, but with the exception of `items`, you'll always get the original property values when calling a getter directly on a `SectionStackSection`.

  Additional SectionHeader properties set on the SectionStackSection not explicitly documented, such as "iconAlign" or "prompt", are supported - use `setAttribute()`.

      Custom controls to be shown on top of this section header.

      These controls are shown in the `SectionHeader.controlsLayout`.

      Note that this is an init-time property. If you need to dynamically change what controls are displayed to the user, we would recommend embedding the controls in a Layout or similar container.

      Base filename of the icon that represents open and closed states. The default settings also change the icon for disabled sections, so a total of four images are required (opened, closed, Disabled_opened, Disabled_closed).

      Not shown if `canCollapse` is false.

      Parameters:

      Identifier for the section. This can be used later in calls to `SectionStack` APIs such as `SectionStack.expandSection()` and `SectionStack.collapseSection()`. Note that if no name is specified for the section, one will be auto-generated when the section is created. This property should be a string which may be used as a valid JavaScript identifier (should start with a letter and not contain space or special characters such as "*").
      Parameters:

      Returns:
        String

    - #### setExpanded

          public void setExpanded(java.lang.Boolean expanded)

      Sections default to the collapsed state unless `showHeader` is set to `false` in which case they default to the expanded state. This attribute allows you to explicitly control the expand/collapse state of the section by overriding the above default behavior.
      Parameters:
        `expanded` - expanded Default value is false

    - #### setHidden

          public void setHidden(java.lang.Boolean hidden)

      Sections default to the visible state. This attribute allows you to explicitly control the visible/hidden state of the section by overriding the above default behavior.
      Parameters:
        `hidden` - hidden Default value is false

    - #### setItems

          public void setItems(Canvas... items)

      Assign a new set of Canvases to this section. These Canvases will be shown and hidden together.
      Parameters:
        `items` - list of Canvases that constitute the section

    - #### getItems

          public Canvas[] getItems()

      Return the items in this SectionStackSection
      Returns:
        the items in this SectionStackSection

    - #### addItem

          public void addItem(Canvas item)

      Adds a new Canvas to this section, at the end.
      Parameters:
        `new` - Canvas to add as item

    - #### getSectionStack

          public SectionStack getSectionStack()

    - #### getSectionHeader

          public SectionHeader getSectionHeader()

      Once a SectionStackSection has been applied to a SectionStack, this method may be used to return a pointer to the SectionHeader for this section
      Returns:
        the SectionHeader for the section

    - #### getID

          public java.lang.String getID()

      Optional ID for the section. If `useGlobalSectionIDs` is true, this property will be applied to the generated SectionStackHeader widget as a standard widget ID, meaning it should be unique within a page.

      Backcompat Note: Section stack sections may be uniquely identified within a stack via the `name` attribute (introduced in Jan 2010). Prior to this, the section ID attribute was used in this way (and would not be applied to the section header as a widget ID). For backwards compatibility this is still supported: If `section.name` is unspecified for a section but `section.ID` is set, the ID will be used as a default name attribute for the section. For backwards compatibility we also disable the standard behavior of having the `section.ID` being applied to the generated section header (thereby avoiding the page-level uniqueness requirement) by defaulting `useGlobalSectionIDs` to false.

      Returns:
        String

    - #### setID

          public void setID(java.lang.String ID)

      Optional ID for the section. If `useGlobalSectionIDs` is true, this property will be applied to the generated SectionStackHeader widget as a standard widget ID, meaning it should be unique within a page.

      Backcompat Note: Section stack sections may be uniquely identified within a stack via the `name` attribute (introduced in Jan 2010). Prior to this, the section ID attribute was used in this way (and would not be applied to the section header as a widget ID).

For backwards compatibility we also disable the standard behavior of having the `section.ID` being applied to the generated section header (thereby avoiding the page-level uniqueness requirement) by defaulting `useGlobalSectionIDs` to false.

      Parameters:
        `ID` - ID Default value is null
