In computing with graphical user interfaces, a drop-down list is a user interface control GUI element, similar to a list box, which allows the user to choose one value from a list. When a drop-down list is inactive, it displays a single value. When activated, it displays 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, including web design.
