     /**
     * RadioSelectInputWidget is a {@link OO.ui.RadioSelectWidget RadioSelectWidget} intended to be used
     * within an HTML form, such as a OO.ui.FormLayout. The selected value is synchronized with the value
     * of a hidden HTML `input` tag. Please see the [OOUI documentation on MediaWiki][1] for
     * more information about input widgets.
     *
     * This and OO.ui.DropdownInputWidget support the same configuration options.
     *
     *     @example
     *     // Example: A RadioSelectInputWidget with three options
     *     var radioSelectInput = new OO.ui.RadioSelectInputWidget( {
     *         options: [
     *             { data: 'a', label: 'First' },
     *             { data: 'b', label: 'Second'},
     *             { data: 'c', label: 'Third' }
     *         ]
     *     } );
     *     $( 'body' ).append( radioSelectInput.$element );
     *
