$obj = $this->widget('Widget_Metas_Category_List');
if($obj->have()){
    while($obj->next()){
        echo '<strong>'.$obj->name.'</strong>';
        echo '<ul>';
        $this->widget('Widget_Archive@'.$obj->name, 'type=category', 'mid='.$obj->mid)->to($categoryPosts);
        while ($categoryPosts->next()) {
            echo '<li>'.$categoryPosts->title.'</li>';
        }
        echo '</ul>';

    }
}else{
    echo '无分类';
