/include/taglib/channelartlist.lib.php

修改为以下内容

这样就可以实现了

在同一栏目分别调用

大栏目下 第一个子栏目{dede:channelartlist limit='0,1'} {dede:arclist row='6'}{/dede:arclsit}{/dede:channelartlist}

大栏目下 第二个子栏目{dede:channelartlist limit='1,1'}{dede:arclist row='6'}{/dede:arclsit}{/dede:channelartlist}

上面就可以在一个模板中调用

如果在子栏目下调用同级栏目的信息

{dede:channelartlist type='reid' limit='0,1'}{dede:arclist row='6'}{/dede:arclist}{/dede:channelartlist}
