The ShowNavigationItem Action is displayed via the navigation control on the main Window. The navigation control comprises the navigation items. This node defines these items. You can add items by selecting the Add Item menu item in the context menu.

You can add child nodes to the NavigationItems node in code. Use the DefaultClassOptionsAttribute or NavigationItemAttribute attribute for this purpose.

This interface is a part of the Application Model infrastructure. You do not need to implement this interface in most cases.

To customize the default content of this node, implement a Generator Updater for the NavigationItemNodeGenerator Nodes Generator.
