Full Active Highlighting

I noticed this is an issue with menus in general in Drupal - it doesn't allow full active highlighting, at least with the sites I've built.

Here's some code below which i've injected to the following file (nice_menus.module ~ line 317):

$link_arr = explode("/",substr($_SERVER['QUERY_STRING'],2));
     
      if (drupal_get_normal_path($menu_item['link']['href']) == $link_arr[0])
      {
         // $class .= ' expanded';
         $menu_item['link']['localized_options']['attributes']['class'] = 'active';
      }
