织梦让channelartlist标签里的channel支持currentstyle

<div>

    <ul>

        {dede:channelartlist row=7 typeid=top currentstyle=current}

        <li class="{dede:field.currentstyle/}">

            <a href="{dede:field.typeurl/}">{dede:field.typename/}</a>

            <ul>

                {dede:channel type='son' noself='yes' row='10' currentstyle="<li><a href='~typelink~'>~typename~</a></li>"}

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

                {/dede:channel}

            </ul>

        </li>

        {/dede:channelartlist}

    </ul>

</div>
