Are Linked Selects Doable in RoR?

[skeeterbug]

linked selects are critical to my application. for those who don't know a linked select updates as the select box it linked to updates.

for example select 1 is "California", then select 2 will list all the cities in California.

change select 1 to Washington and select 2 will change to list all the cities in Washington.

I use a php forms class to achieve this functionality right now.

Does RoR offer it?

Yes they are possible. here is an article on one technique that uses ajax to grab the secondary list contents based on what was selected in the first one.
