Adrop-down list (DDL),drop-down menu or justdrop-down[1]– also known as adrop menu,pull-down list,picklist – is agraphical control element, similar to alist box, that allows the user to choose one value from a list either by clicking or hovering over the menu. When a drop-down list is inactive, it displays a single value. When activated, it displays (drops down) a list of values, from which the user may select one. When the user selects a new value, the control reverts to its inactive state, displaying the selected value. It is often used in the design of graphical user interfaces, includingweb design.
This type of control is called a "pop-up menu" on theMacintosh platform;[2] however, the term "pop-up menu" is used to refer tocontext menus in other GUI systems. The Macintosh also has the notion of "pull-down menus". The distinction is that, when the menu is closed, a pop-up menu's title shows the last-selected item while a pull-down menu shows a static title like a menu in the menu bar. Thus, the uses are different—pop-up menus are used to select a single option from a list while pull-down menus are used to issue commands or in cases where multiple options can be selected.
Inweb forms, theHTML elements<select> and<option> are used to display a drop-down menu:[3]
<select><option>option1</option><option>option2</option><option>option3</option></select>
GTK 4 have theGtk.DropDown widget.[4]
