ActiveScaffold :form_ui select

If I have two :form_ui select boxes, how can I make the first select
box reload the values in the second? For example,

---> [Car Maker]
-------> [Car Model]

When I change a value in the 'Car Maker' select box, I want to display
values in the 'Car Model' select box that only belong_to that Car

I read another post in this group that recommended using
options_for_association_conditions. I read the documentation but the
sample code doesn't fit my needs.

Please help.

Thanks in advance,

btw - A small code sample would make my day :slight_smile:

I am need to do something exactly like this too. Any solutions out
there. My "basic" Rails/Ruby knowledge is not getting me anywhere.

Help very much appreciated.
