The following example shows how to display multiple collections and items as one list using the CompositeCollection class. In this example, GreekGods is an ObservableCollection<T> of GreekGod custom objects. Data templates are defined so that GreekGod objects and GreekHero objects appear with a gold and a cyan foreground color respectively.
