As far as I know, this method is applicable to all menus in the menu manager.

据我所知，这种方法适用于菜单管理中所有类型的菜单。

A menu manager can contain items, other menu managers (for submenus), and separators.

菜单管理器可包含菜单项、其它菜单管理器(用于子菜单)和分隔符。

youdao

Once you have created a menu manager, it can be represented by either a bar menu, a context menu (in other words, a pop-up menu), or a toolbar drop-down menu.

一旦创建了菜单管理器，就可以用菜单栏、上下文菜单(也就是弹出菜单)或工具栏下拉菜单表示它。
