Meta order

Hi, we have the context parameter for meta boxes, which you can use to load meta boxes with priority. For meta boxes with the same context, you can try setting keys for meta boxes array, like this:

add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
    $meta_boxes['1_general'] = ...;
    $meta_boxes['2_social'] = ...;
    return $meta_boxes;
} );
