Gets or sets a value that indicates whether the menu selects different item containers, depending on the type of the item in the underlying collection or some other heuristic.
Assembly: PresentationFramework (in PresentationFramework.dll)
This property is useful if you want to create a menu by binding to a collection. The item container is the UI element that displays the object in a collection. If you want to bind to a collection to create a menu that contains MenuItem objects and Separator objects, set the property to true and create an ItemContainerTemplate for each type of object in your collection. Each ItemContainerTemplate must contain either a MenuItem or a Separator.
