phpcms v9 多级下拉菜单的子栏目调取办法

此处为三级菜单的写法,同理,可以得出无限循环子栏目,代码如下:
 
<ul>
{pc:content action="category" catid="0" num="12" siteid="$siteid" order="listorder ASC"}
 {loop $data $c}
    <li><a href="{$c['url']}">{$c['catname']}</a>
       <ul>
  {loop subcat($c['catid']) $c2}
     <li><a href="{$c2['url']}">{$c2['catname']}</a>
      <ul>
       {loop subcat($c2['catid']) $c3}
           <li><a href="{$c2['url']}">{$c3['catname']}</a></li>
           {/loop}  //Cuoxin.com
      </ul>
     </li>
      {/loop}
  </ul>
   </li>
{/loop}
{/pc}
</ul>
