Dynamic Values for DropDowns

P: 4
I have a page with all form field to take input from user.
ex : when user selects a Country automatically all the states within that country should be populated in second list box with values(states) fetched from database.
and if I select state again all the cities under this state would appear in 3rd drop down.. like that...

I know Ajax will do this thing.. But can anyone point me to the sample code..
