if ($(_parent).hasClass('item'))
      {
        $(_parent)[selected && $(this).closest('table').find('.item:not(.selected)').length == 0 ? 'addClass' : 'removeClass']('selected');
        var _grandparent = $(_parent).parent().parent().parent().parent().parent().siblings();
        if ($(_grandparent).hasClass('item')) $(_grandparent)[selected &&  $(_parent).closest('table').find('.item:not(.selected)').length == 0 ? 'addClass' : 'removeClass']('selected');
      }
