文章模块列表循环，实现第一个（即第首条信息高亮），有什么好办法。上面代码判断在栏目循环里面可以更具栏目ID来，但用到栏目下面的文章去用就行不通，

试了下，以下代码可以实现，但调不出文章内容content

                      <div class="tab product_con" role="tabpanel">
                          <!-- Nav tabs -->
                          <ul class="nav nav-tabs" role="tablist">
         {list action=module catid=$catid field=id,title,url,thumb,updatetime,description,keywords,hits order=updatetime}
         <li role="presentation" class="{if $key+1==1} active {/if}"><a href="{$t.url}#Section{$t.id}" aria-controls="home" role="tab" data-toggle="tab">{dr_strcut($t.title, 6)}</a></li>
         {/list}       
                          </ul>
                          <!-- Tab panes -->
                          <div class="row tab-content tabs">
         {list action=module catid=$catid field=id,title,url,thumb,updatetime,description,keywords,hits order=updatetime}
          <div role="tabpanel" class="tab-pane fade in {if $key+1==1} active {/if}" id="Section{$t.id}">
           {$t.description}{$t.title}
          </div>
         {/list}      
                          </div>
                      </div> 

使用连表查询，又有个问题是，首次打开，不高亮，点击后才高亮，这个情况该如何解决。

                      <div class="tab product_con" role="tabpanel">
                          <!-- Nav tabs -->
                          <ul class="nav nav-tabs" role="tablist">
         {list action=sql module=news sql='SELECT * FROM dr_1_news JOIN dr_1_news_data_0 ON dr_1_news.id = dr_1_news_data_0.id WHERE dr_1_news.catid =$catid  order by updatetime desc' return=t} 
         <li role="presentation" class="{if $key+1==1} active {/if}"><a href="{$t.url}#Section{$t.id}" aria-controls="home" role="tab" data-toggle="tab">{dr_strcut($t.title, 8)}</a></li>
         {/list}       
                          </ul>
                          <!-- Tab panes -->
                          <div class="row tab-content tabs">
         {list action=sql module=news sql='SELECT * FROM dr_1_news JOIN dr_1_news_data_0 ON dr_1_news.id = dr_1_news_data_0.id WHERE dr_1_news.catid =$catid  order by updatetime desc' return=t} 
          <div role="tabpanel" class="tab-pane fade in {if $key+1==1} active {/if}" id="Section{$t.id}">
           {$t.content}
          </div>
         {/list}      
                          </div>
                      </div>
