Bundles are repeatable groups of fields.

Unfortunately it's not (yet) possible to add file, image, repeatable fields to a bundle. This is because these fields are Vue fields, and Vue will not update when the fields are added (via AJAX). This is a known bug in Cuztom, if you know a solution, please open an issue on Github or contact me.

$box = register_cuztom_meta_box( $id, $post_type, array(
    'fields' => array(

            'id'     => '_data_bundle',
            'type'   => 'bundle',
            'fields' => array(
                // Fields


) );
