foreach ( $items as $key=>$item ) {

if($item->object == 'category') {

//$cat = get_category_by_slug($slug);

$catID = isset($item->object_id) ? $item->object_id : false;

if($catID && $item->post_parent!=0) {

$a=wt_get_category_count($catID);

$items[$key]-&gt;title.= '<span class="num">'.$a.'</span>';

}

}

}

return $items;
