怎样显示当前耳机栏目下的三级栏目，现在三级栏目全部显示出来了！

代码：

{category module=share pid=2 return=t1}
    {category module=share pid=$t1.id return=t2}
      <div class="lm_lb">
        <h3>{$t2.name}</h3>
        <ul class="row">
  {module catid=$t2.id order=updatetime pagesize=100} 
          <li class="col-lg-3 col-md-6 col-12">
            <div class="n_r"><a href="{$t.url}">
              <div class="t_b"><img src="{dr_get_file($t.thumb)}"></div>
              <div class="w_z">
                <h3>{$t.title}</h3>
                <p>{dr_strcut($t.description, 100)}</p>
              </div>
            </a></div>
          </li>
         {/module}
        </ul>
