This class includes the fields that display a finite list of values from which end users can select a single value. There are three subclasses—RadioField, ListField, and OptionField—that display and manipulate the choices available to the user in different ways.

The valid choices for the field are contained in the ValueList attribute of the ChoiceField class. This attribute refers to a ChoiceList object that contains the valid set of values allowed for the field. Each value has text and an associated integer value.
