这个用法只限于在一级和二级导航在一块的情况，如果是分开的，就去看另一篇无极限分类 

// 递归：菜单分类显示
    public function levelList($table ='mvc_category', $id = 0,$data_list = [],$level=0){

        // 查询出来所有的一级
        $data = Db::table($table)->where([
            'fid'=>$id
        ])->select();

        // 组装数据
        foreach($data as $k => $v){
            $data_list[$v['id']]['name'] = str_repeat('  ',$level).'|-'.$v['name'];


            $data_list[$v['id']]['id'] = $v['id'];

            $data_list[$v['id']]['fid'] = $v['fid'];

            if(isset($v['type'])){
                $data_list[$v['id']]['type'] = $v['type'];
            }

            if(isset($v['module'])){
                $data_list[$v['id']]['module'] = $v['module'];
            }

            $data_list[$v['id']]['level'] = $level;

            $data_list = $this->levelList($table,$v['id'],$data_list,$level+1);


        }

        return $data_list;


    }
