      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 `DynamicForm.sectionVisibilityMode` to "mutex".

    `DynamicForm.getSectionVisibilityMode()`

    - #### setDefaultProperties

          public static void setDefaultProperties(SectionItem sectionItemProperties)

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

        `SGWTProperties`
