pull-down menu - technical definition

Also called a "drop-down menu" or "pop-down menu," the common type of menu used with a graphical user interface (GUI). Clicking a menu title causes the menu items to appear to drop down from that position and be displayed. Options are selected either by clicking the menu item or by continuing to hold the mouse button down and letting go when the item is highlighted.

On Web pages, menu items are often displayed automatically as soon as the cursor is positioned over the menu title. JavaScript is widely used to implement pull-down menus on the Web. See JavaScript.
