When To Use
IRootLevelMenu is an indicator interface that is used only to indicate to the application that the menu should be treated as a root menu. This means that the menu will appear in the Menus command category in the Customize dialog box. If you are creating a root menu you would implement both IMenuDef and IRootLevelMenu.
