Create a radio button field

You use radio buttons when there can be only one choice. For example, you can uncheck the check boxes by clicking them again; however, the only way to uncheck radio buttons is to clear a form data either by using Reset Form Field (Form > Recognize Forms > Recognize Forms) or clicking a then-created Reset form button. See To create a Reset form button for details.

You can create a group of radio buttons with the same field name if you want the user to select only one choice among a set of choices. Though radio buttons in the same group have the same field name, each button has a different export value.
