然后，内容——模型管理——选择一个模型添加新字段，如图。

最后，在要调用产品筛选的栏目模板页添加标签 ，如下。

<span>性别：</span>    
{loop filters('xingbie',$modelid) $r}  
{$r\[menu\]}  
{/loop}

{php $sql = structure\_filters\_sql($modelid)}  
{php $urlrule = makeurlrule()}  
    {pc:content action="lists" where="$sql" catid="$catid" num="10" order="id DESC" page="$page"  urlrule="$urlrule"}  
      
        <ul class="photo-list picbig">  
            {loop $data $r}  
            <li>  
            <div class="img-wrap">  
            <a href="{$r\[url\]}"><img src="{thumb($r\[thumb\],150,112)}" width="150" height="112" alt="{$r\[title\]}"/></a>  
            </div>  
            <span style="color:{$r\[style\]}">{str\_cut($r\[title\],28)}</span>  
            </li>  
            {/loop}  
        </ul>  
        <div id="pages" class="text-c">{$pages}</div>  
    {/pc}
