Use this code example to change the responsive breakpoint in a Likert field.

add_filter('frm_surveys_likert_responsive_breakpoint', 'change_likert_responsive_breakpoint', 10, 2);
function change_likert_responsive_breakpoint( $min_width, $args ) {
	$field_id = is_object( $args['field'] ) ? $args['field']->id : $args['field']['id'];
	if ( 728 == $field_id ) { // Change 728 to the Likert field ID. Remove this check if you want to apply this to all Likert fields.
		$min_width = 600; // Adjust this value.
	}
	return $min_width;
}
