请问使用select标签如何制作出多级的下拉列表(非联动)？

Question

如图所示，当把鼠标移动到A上的时候，右边弹出第二级选项(如条件1，条件2)，当把鼠标放到第二级选项上时，可以弹出第三级选项(如附加条件1，附加条件2等)。

请问这样的效果仅用select标签可以实现么，或是要加上其他方面的技巧，希望有人能够帮忙解答，如果能够附上相应的代码就最好了。

{"errorDesc":"成功","data":[{"areaId":"440604","areaName":"禅城区","parentAreaId":"440600","ShortName":"禅城","LevelType":3,"AreaCode":"0757","Zipcode":"528000","Lng":"113.1228","Lat":"23.00842","PinYin":"Chancheng","AreaStatus":1},{"areaId":"440600","areaName":"佛山市","parentAreaId":"440000","ShortName":"佛山","LevelType":2,"AreaCode":"0757","Zipcode":"528000","Lng":"113.122717","Lat":"23.028762","PinYin":"Foshan","AreaStatus":1},{"areaId":"440000","areaName":"广东省","parentAreaId":"100000","ShortName":"广东","LevelType":1,"AreaCode":"","Zipcode":"","Lng":"113.280637","Lat":"23.125178","PinYin":"Guangdong","AreaStatus":1},{"areaId":"100000","areaName":"中国","parentAreaId":"0","ShortName":"中国","LevelType":0,"AreaCode":"","Zipcode":"","Lng":"116.3683244","Lat":"39.915085","PinYin":"China","AreaStatus":0}],"errorCode":1,"isError":0}好比如地址联动加载对应数据的，数据返回格式为以上数据（返回自己所有需要的数据，数据归类自己写函数维护），像以上的数据，广东是中国的子级，佛山是广东的子级，禅城区是佛山的子级，它们相关联起来通过areaId和parentAreaId关联起来！所以这样的需求，数据库设计是关键，再者数据的归类函数的实现！
