Render a radio button input field.
Examples In this example, a radio control is displayed with a list of genders. The gender list is built from attribute id=genders. The framework calls getGenders() which will return a Map. For examples using listKey and listValue attributes, see the section select tag. The default selected one will be determined (in this case) by the getMale() method in the action class which should retun a value similar to the key of the getGenters() map if that particular gender is to be selected.
<s:action name="GenderMap" var="genders"/> <s:radio label="Gender" name="male" list="#genders.genders"/> <@s.radio name="car" list={"ford": "Ford Motor Co", "toyota": "Toyota"} listKey="key" listValue="value" />
