{dede:field name='typename'/} 
 {dede:channel type='son' noself='yes'} 
·[field:typename/]
 {/dede:channel} 
 
 {/dede:channelartlist}

It’s actually very simple:

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

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

and change it to

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

That’s it.
