放下填充较小类别的菜单 [英] Drop Down Menus That Populate Smaller Categories

问题描述

我正在阅读另一个表单，并建议客户端使用下拉类别。这正是我想在我的网站上做的事情。我希望我的客户能够选择Country，Prov，City。这是论坛的建议：



一个选项是有多个选择框（例如汽车制造，汽车模型）。从一个盒子中选择一个选项并且它在另一个框中填充了一组较小的选项。



如果你能告诉我这些代码是做什么的那就太棒了!!



谢谢，

Tanya

I was reading another form and it was suggested that the client uses categories for the drop down. This is exactly what I am trying to do on my site. I would like my customers to be able to select Country, Prov, City. This is the suggestion from the forum:

"One option is to have multiple selection boxes (eg Make of car, model of car). Choose an option from one box and it populates a smaller set of options in another box."

If you can tell me what the code is to do so that would be great!!

Thanks,
Tanya
