CSS style for pages which have subpages

Permalink
Is it possible to modify the AutoNav template that it would add a class for all pages which have subpages?

I found the code which adds a class for pages for the dropdown menu, but that works only for the active page:
if ($ni->hasSubmenu) {
   //class for items that have dropdown sub-menus
   $classes[] = 'nav-dropdown';
}


Can this be done for all pages which have subpages?
