i added this option by a little code and it worked like a charm!
in SubmenuModel.php >
just add (‘menu_order’ => ‘Menu Order’) to this part of script.
private static $order_options = array(
‘tax’ => array(
‘name’ => ‘Name’,
‘slug’ => ‘ Slug’,
‘count’ => ‘Tax Count’,
‘id’ => ‘ID’,
‘none’ => ‘None’,
‘menu_order’ => ‘Menu Order’
),
thank you again …
