    {dede:channelartlist typeid='3' }
    <dl class="zzProduct_Class_Title"><a href="{dede:field name='typelink'/}" title="{dede:field name='typename'/}">{dede:field name='typename'/}</a></dl>
    <dl class="zzProduct_Class_List">
        {dede:channel type='son'noself='yes'}
        <dt><a href="[field:typelink/]" title="[field:typename/]">[field:typename/]</a></dt>
        {/dede:channel}
