制作dedecms5.7下栏目列表三级联动

测试页面：member/templets/archives_sg_add.htm
效果：



PS：没有什么技术含量，通过自学解决问题而已。
member/archives_sg_add.php添加调用：
require_once(dirname(__FILE__)."/GetArcTypeList.php"); 
 member/templets/archives_sg_add.htm  在隶属栏目：添加代码：
           隶属栏目：
                             $typeOpti*****1 = GetOptionListM1(0,$channelid);
            echo "\r\n";
            echo "请选择栏目...\r\n";
            echo $typeOpti*****1;
            echo "";
        ?> //一级栏目
         //二级栏目列表
//三级栏目列表
        *
