Let me show you a piece of code first:

The code is as follows:

{dede:channelartlist typeid = 3} 
<li class="sub_ul1_li"><a href="{dede:field name=&#39;typeurl&#39;/}" class="publica">{dede:field name=&#39;typename&#39;/}</a> 
<ul class="sub_ul2 hide"> 
{dede:channel type=&#39;son&#39; noself=&#39;yes&#39;} 
<li><a href="[field:typelink/]" class="publica">·[field:typename/]</a></li> 
{/dede:channel} 
</ul> 
</li> 
{/dede:channelartlist}

The meaning of this code is to query the column id 3 The sub-column then queries the sub-column of the sub-column. The effect is as shown in the figure:

But there will be a problem, that is, if the column has no sub-column, its column of the same level will be taken, so how to solve {dede:channel type='son'} What’s the problem with selecting columns at the same level when there are no sub-columns?

It’s actually very simple:

Open: include\taglib\channel.lib.php file.

Find

if($type=='son' && $reid!=0 && $totalRow==0)

and change it to

if($type=='son' && $reid!=0 && $totalRow==0 && $noself=='')

That’s it.
