    public class MultiboxTag

extends BaseHandlerTag

Tag for input fields of type "checkbox". This differs from CheckboxTag because it assumes that the underlying property is an array getter (of any supported primitive type, or String), and the checkbox is initialized to "checked" if the value listed for the "value" attribute is present in the values returned by the property getter.
