Four options on a radio button. When a new option is chosen, the previously chosen option is unselected.
A radio button or option button[citation needed] is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options.[1] The singular property of a radio button makes it distinct from checkboxes, where the user can select and unselect any number of items.
Radio buttons are arranged in groups of two or more and displayed on screen as, for example, a list of circular holes that can contain white space (for unselected) or a dot (for selected). Each radio button is normally accompanied by a label describing the choice that the radio button represents. The choices are mutually exclusive; when the user selects a radio button, any previously selected radio button in the same group becomes deselected (making it so only one can be selected). Selecting a radio button is done by clicking the mouse on (or touching the screen over) the button, or the caption, or by using a keyboard shortcut.
