[Ajax / PHP] - comboBox City / State

Hello,
I have been wondering... if someone with high skills in php could implement it.
I mean, i have three fields into classipress (search bar) i am using wp custom search mod by 'Don Benjamin' here's the link:

http://wordpress.org/extend/plugins/...fields-search/

I am attaching a complete comboBox [city/state] that i searched on google's page in pt_BR;
The idea is when i select a state_field -> ajax loads "cities from that state_field" -> shows the cities.

here's the demo:

Here's the attachment:
If somebody knows how to figure out please share with us
Thanks in advance,

PS: I think it is very important into a classified system, should add on classipress

Mzah.

Thanks
