2、在模板里用</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:xhtml;">
{dede:channel function='getProductTree(2)'}{/dede:channel}
</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
调用即可。这里getProductTree(2)中的 2 是产品展示的栏目ID。如果你的是其他的，请作相应修改。</p>
