在模板调用实例：

{dede:channel type='son' typeid='3'}

              [field:typename/]

                    <ul>

                    [field:sonchannel0]

                    <li><a href="[field:typelink/]">[field:typename/]</a></li>

                         [/field:sonchannel1]

                    [/field:sonchannel0]

                    </ul>

 {/dede:channel}

{dede:channelartlist} {dede:field name='typename'/} {dede:arclist titlelen='60' row='8'} [field:typename /][field:title /] {/dede:arclist} {/dede:channelartlist}css你会吧，自己定义下就好了

channel 不支持row

你可以使用channelartlist row='1,3' 这样他会取前面3个， 你可以看channelartlist的标签代码，它是支持的
