An HTML form menu lets a visitor select one or more items from a list. Menus are useful when you have a limited amount of space, but need to display many items. Theyre also useful when you want to control the values returned to the server. Unlike text fields where users can type anything they want, including invalid data, you set the exact values returned by a menu.
You can insert two types of menus in a form: a menu that drops down when the user clicks it or a menu that displays a scrollable list of items that can be selected. This type is called a list menu.
A menu appears in the document.
