DTcms.Web.UI\Label\category.cs中

添加下面代码

   /// <summary>

        /// 返回所有类别

        /// </summary>

        /// <returns></returns>

        protected DataTable get_category()

        {

            BLL.channel bll = new BLL.channel();

            return bll.GetList(, "", "  sort_id desc").Tables[];

        }

模版调用：

   <%set DataTable categorylist=get_category()%>

      <%loop category categorylist%>

      <a href="{category[name]}/{category[name]}_index.html">{category[title]}</a>

      <%/loop%>

链接地址看后台设置，灵活调用

后续更改：有不需要展示的频道

<ul id="navigation">

    <li><a href="<%linkurl("index")%>" title="{site.seo_title}">首页</a></li>

   <%set DataTable categorylist=get_category()%>

      <%loop category categorylist%>

          <%if {category[title]}!="关于我们" %>

         <li onmouseover="displaySubMenu(this)" onmouseout="hideSubMenu(this)">

         <a href="/{category[name]}_index.html">{category[title]}</a>

         <ul>

      <%set DataTable arc_categorylist=get_category_list(0,{category[id]})%>

         <%loop arc_category arc_categorylist%>

        <li> <a href="/{category[name]}/list-{arc_category[id]}.html">{arc_category[title]}</a></li>

         <%/loop%>

         </ul>

         </li>

         <%/if %>

      <%/loop%>

      </ul>
