织梦dede调用四级栏目
做啦
织梦调用四级子栏目，首先需要修改文件：\include\taglib\channel.lib.php，请将以下代码全部复制替换上述文件：
2、在模板中调用实例：

2、在模板中调用实例：
01 {dede:channel type='son' typeid='3'}
02 [field:typename/]
03 <ul>
04 [field:sonchannel0]
05 <li><a href="[field:typelink/]">[field:typename/]</a></li>
06 [field:sonchannel1]
07 <li><a href="[field:typelink/]">---[field:typename/]</a></li>
08 [field:sonchannel2]
09 <li><a href="[field:typelink/]">===[field:typename/]</a></li>
10 [field:sonchannel3]
11 <li><a href="[field:typelink/]">===[field:typename/]</a></li>
12 [/field:sonchannel3]
13 [/field:sonchannel2]
14 [/field:sonchannel1]
15 [/field:sonchannel0]
16 </ul>
17 {/dede:channel}
