Menus are used for selecting functions or for navigation (see DIN EN ISO 9241-161: 8.26).
A menu has several menu items which are usually arranged horizontally and adjacent to each other. A menu item can have a sub-menu. The menu items of a sub-menu are arranged vertically. Sub-menus can be nested several times, i.e. a menu item in a sub-menu can also have a sub-menu. It is only possible to display one sub-menu per hierarchy level. A menu can contain menu items that can be selected like check boxes or radio buttons. The menu items can be grouped. The label of the groups cannot be selected.
