public class RadioButtonTag
extends AbstractSingleCheckedElementTag

The <radiobutton> tag renders an HTML 'input' tag with type 'radio'.

Rendered elements are marked as 'checked' if the configured value matches the bound value.

A typical usage pattern will involved multiple tag instances bound to the same property but with different values.
