商业源码 在织梦DEDECMS列表页调用指定栏目ID 并且有分页功能，该怎么实现
一、修改文件：\include\taglib目录下的channellibphp，请将以下代码全部复制替换上述文件
<phpfunction lib_channel(&$ctag,&$refObj)

二、在模板调用
实例：
{dede:channel type='son' typeid='改成你的大栏目ID'}[field:typename/]
<ul>
[field:sonchannel0]
<li><a href="[field:typelink/]">[field:typename/]</a></li>
[field:sonchannel1]
<li><a href="[field:typelink/]">---[field:typename/]</a></li>
[field:sonchannel2]
<li><a href="[field:typelink/]">===[field:typename/]</a></li>
[field:sonchannel3]
<li><a href="[field:typelink/]">===[field:typename/]</a></li>
[/field:sonchannel3]
[/field:sonchannel2]
[/field:sonchannel1]
[/field:sonchannel0]
</ul>
{/dede:channel}
模板调用 [field:sonchannel0] [/field:sonchannel0] 这个是用来取子栏目用的（使用[sonchannel+数字] 作为标签名是为了防止嵌套的时候无法正确解析标签）
这个的作用就是当你的栏目有很多子栏目 无限分级的时候方便你取子栏目的。
这个主要是靠你的css来实现，这个是可以嵌套调用的，调用顶级栏目，里面嵌套调用子栏目，不过要实现你鼠标指到顶级栏目，显示出你的子栏目，这个是靠你的css了！这方面的css网上有的，导航代码，你网上找找！
解决在一个空栏目中，调用已有信息栏目的内容：
在栏目管理中，修改 空栏目的属性，如图：
在栏目交叉中选择手工指定交叉栏目ID，就可以了。
