1、找到 include/taglib/channel.lib.php 文件，用下面代码替换这个文件里面的所有内容,以免出错，请先备份一下原文件。

?>2、将以下内容复制到你需要调用的模板中。
Products List
//导航此处才开始
{dede:channelartlist typeid='top' row='8'}
{dede:field name='typename'/}
{dede:channel type='son'}//注意：此处不要加typeid函数，不然它会只调用你指定的ID分类;
[field:typename/]
[field:sonchannel0]
[field:typename/]
[field:sonchannel1]
---[field:typename/]
[field:sonchannel2]
===[field:typename/]
[field:sonchannel3]
