The RadioField class displays a set of buttons that represent a set of choices. The field displays all the choices on the screen at the same time. This class is useful for lists that contain only a few choices.

The choices are stored in the ValueList attribute inherited from the ChoiceField class. If you change the ValueList attribute dynamically, the radio field adjusts as needed on the form to accommodate the changes.

For more information, see the ValueList Attribute).
