+A single radio button performs the same basic function as a @ref{check-button}, as its position in the object hierarchy reflects. It is only when multiple radio buttons are grouped together that they become a different user interface component in their own right.
+
+Every radio button is a member of some group of radio buttons. When one is selected, all other radio buttons in the same group are deselected. A @ref{radio-button} is one way of giving the user a choice from many options.
+
+To group radio buttons into one group, set @SlotRef{radio-button,group} to one of the radio buttons of the group.
