Creates a radio button that can be turned on and off. When a number of radio buttons share
the same control name, only one button within the group can be “on” at one time, and all the
others are “off.” This makes them different from checkboxes, which allow multiple choices
to be selected within a group. Only data from the “on” radio button is sent when the form is
submitted:
