class: Menu

[22:7] extends: MenuItem

The Menu class wraps the JavaFX Menu control, a popup list of selectable items that is added to a MenuBar or nested inside another Menu as a submenu. Menu extends MenuItem, which means it inherits click-event support and optional graphic icons alongside its text label. When a user clicks a Menu entry in the bar it opens and displays its child MenuItems or nested Menus. The showing pseudo-class is applied automatically by JavaFX while the menu popup is open, allowing stylesheet rules to change appearance during that state.
