The menu-item class lets you create individual menu items. These items can be passed to menu-components or menus via the :items
keyword. Using this class, you can assign different callbacks to different menu items.
(setq test (make-instance 'menu-item
:title "Test"
:callback 'test-callback))
(setq hello (make-instance 'menu-item
:title "Hello"
:callback 'hello))
(setq group (make-instance 'menu-component
:items (list test hello)))
(contain group)

Remember that each instance of a menu item must not be used in more than one place at a time.
