2.调用

这是我调用的代码 

{dede:channel typeid='1'}

     <li>

      <a class="" href="[field:typeurl/]" title="">[field:typename/]

      <img src="***.gif" /></a>

      <div class="sub">

       <ul>            

        [field:sonchannel0]<li><a href="[field:typeurl/]">[field:typename/]</a></li>[/field:sonchannel0]

       </ul>

      </div>

     </li>

    {/dede:channel}

[field:sonchannel0] 表示下级的菜单 自己改吧
