 *    	]
 *    );
 *
 * @since 1.6.0
 *
 * @param string $name        The field name.
 * @param string $separator   Optional. Set the position of the control separator.
 *                            Available values are 'default', 'before', 'after'
 *                            and 'none'. 'default' will position the separator
 *                            depending on the control type. 'before' / 'after'
 *                            will position the separator before/after the
 *                            control. 'none' will hide the separator. Default
 *                            is 'default'.
