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:
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.
