A menu. A menu typically presents a vertical list of menu items, each of which can be selected by clicking. A menu is either expanded or not expanded. Only one menu can be expanded within a screen at any given time. Clicking outside of the menu typically causes the expanded menu to be no longer expanded. Menus form a tree structure, with exactly one root.
