Staggered filter list - El Forum - 03-12-2009

I am trying to create a page for the user to generate a report. The report analyses by city. Since the list of cities is very long, I would like the user to first select STATE, to reduce the list of cities that the user can choose from.
State: [choose a state]
City : [choose a city (reduced list)]
[Print Report] button
Is this possible with CI? What are the options? Javascript? Server-side?
Thanks in advance.

server side you have to work with a button after the state is selected. javascript you can update the city list as soon as the state is selected using ajax.

you must attach the "onchange" event to the states select , then you have 2 options ,
1.- load the city list with ajax. sending the selected state value and retrieving only the cities that belong to that state
2.- post the form to the server, get the value of the states select and populate the city select according to that value and reaload the page ( actually sending the whole page again to the browser )
