如何在drupal或elgg上使用自定义社区/城市/州进行注册？

Question

I'm implementing a social networking site. I hope to use drupal or elgg and am trying out both. I'm stuck on customizing the registration to include a neighborhood in addition to city and state.

I want to have drop-down menus customize the local information based on the more global information. So, once you choose the state, the city list is populated in a drop-down menu.

I am building a list of the interesting neighborhoods, and can load that into a db table or whatever is convenient.

What do you suggest?

Javascript and/or php is fine.

You're going to want a module like Active Select (Drupal 6 port here) that provides that sort of functionality to the Forms API.
