Meta Box

Yes, of course, here it is:

add_filter( 'rwmb_meta_boxes', 'meta_box_group_demo_register' );

function meta_box_group_demo_register( $meta_boxes )
{

$meta_boxes[] = array(
    'id'     => 'persondetails',
    'title'  => __( 'Person\'s Details', 'your-prefix' ),
    'pages'  => array( 'our_attorneys' ), //post type name
    'fields' => array(

        //group
        array(
            'id'     => 'lawyers_prof_act',
            'name'   => __( 'Professional Activity', 'your-prefix' ),
            'type'   => 'group', // Group type
            'clone'  => true,    // Can be cloned?

            // List of child fields
            'fields' => array(
                array(
                    'name'    => __( 'Activity Title', 'your-prefix' ),
                    'id'      => 'npm_lw_act_title',
                    'type'    => 'text',
                    'columns' => 6, 
                ),

            array(
                'name'    => __( 'Important Resources', 'your-prefix' ),
                'id'      => "npm_lw_act_content",
                'type'    => 'wysiwyg',
                'raw'     => false,
                'options' => array(
                    'textarea_rows' => 4,
                    'teeny'         => true,
                    'media_buttons' => false,
                ),
            ),
                array(
                    'name'    => __( 'Shortcode - [attorney-blog-posts category=  author= ]', 'your-prefix' ),
                    'id'      => 'npm_att_shortcode',
                    'type'    => 'text',
                    'columns' => 6, 
                ),
            ),
        ),
    ),
);

I'm sorry, I should have specified: the wysiwyg editor is broken when using groups WITH the "clone" set to "true" - I do believe it's a js thing but I just can't find it!

Best regards,
