To add a menu, click Menu on the button bar at the bottom of the Interface Builder. Each menu must be added as the child of the menu bar, or as the child of another menu or menu component. In the first case, the new menu is visible on the main menu bar of the interface. Otherwise, it appears as a submenu of the relevant menu.
Newly created menus cannot be selected in the interface skeleton until menu items or components are added to them.
By default, new menus are called
MENU-1
,
MENU-2
and so on, and appear in the interface skeleton as
Menu-1
,
Menu -2
and so on, as relevant. See Performing operations on objects for details on how to change these default names.
