Dynamic SelectBoxes/DropDownLists


I’d like to implement in my project dynamic dropdown lists.
user will select one option from the parent dropdown list, lets say
it’ll be COUNTRY and in the child dropdown will be generated all CITIES
tied with this selected country.

I could then have relevant info in my form. Country and one of its city.

I know, this is not much abour RoR, however it has something to do w/
Ajax. I really like autocomplete feature in RoR and I’m sure this
dynamic dropdowns should be done easy in Ajax too.

any clues…?

thanks and have a great day
