看到没有，其实里面的一级菜单对应二级菜单都是在同一个li里面的，li里面的二级三级呢，都是放在dl的dt和dd标签里面；
然后现在我们看看取出来的category_menu,什么样的数据：
Array
(

然后，数据表是怎么样的数据呢：
Array
(
[0] => Array
(
[category_id] => 211
[category_name] => 鞋柜
[parent_id] => 31
[listorder] => 200
[display] => 1
)
[1] => Array
(
[category_id] => 194
[category_name] => 相框/照片墙
[parent_id] => 189
[listorder] => 200
[display] => 1
)
[2] => Array
(
[category_id] => 193
[category_name] => 帘艺隔断
[parent_id] => 189
[listorder] => 200
[display] => 1
)
[3] => Array
(
[category_id] => 192
[category_name] => 沙发垫套/椅垫
[parent_id] => 189
[listorder] => 200
[display] => 1
)
[4] => Array
(
[category_id] => 191
[category_name] => 地毯地垫
[parent_id] => 189
[listorder] => 200
[display] => 1
)
[5] => Array
(
[category_id] => 190
[category_name] => 桌布/罩件
[parent_id] => 189
[listorder] => 200
[display] => 1
)
数据表数据是酱紫的；
然后，你能写出那个处理数组的方法吗，给你原数据，然后你用迭代处理成你想要的数据，不用太多，6行代码左右，你OK？
代码拷贝多了，人也就变傻了，知不知道？？？
//把栏目分组，以多维数组形式
public function group_category($id = 0)
{
$list=$this->where('display = 1')->order('listorder asc')->select();
$tmp = array();
foreach($list as $v){
if($v['parent_id'] == $id){
$v['childs'] = $this->group_category($v['category_id']);
$tmp[] = $v;
}
}
return $tmp;
