高分请教一个ASP三级分类显示的问题！

[acrmbs]

　　项目总共有三级分类(区县／乡镇／街道)现在问题是：如果我添加信息的时候，如果选中了第三级"街道"，那么其它已添加的信息里没有第三级的也会显示出了第三级街道．同时没有第二级"乡镇"信息的也会显示成我所选中的第二级和第三级分类，这样就成了多个"区县"同一个街道或多个"区县"同一个"乡镇""街道的问题"但是修改和查询时每个数据的分类都是正确的．
如下图：请大家帮忙补一下代码谢谢!

你添加信息的代码要修改，不是修改显示的。。 添加的时候选择乡镇街道时没有下一级节点的select要清空，不保存这些没有下一级街道的信息 例如你选择镇的时候，清空镇街道select的option，然后再根据是否有下一级节点信息添加option，同理选择镇的时候清空街道的option
