Take a look into XMLHTTPRequest http://www.google.com/search?q=xmlhttprequest
it will allow you to
send a request to a page after the first drop down is selected without having
to do a page refresh.
Just a thought.

I've done something similar using JavaScript on our site for lists of makes
models of cars. The first box displays a list of makes, and depending on the
make selected, the second displays all the models for that make. That list is
huge, but here's an abbreviated version using a few makes:
That does not work on some browsers most notably Opera, i beleive. So
be careful of this if you want cross browser support. Alternatively
you could use a hidden iframe as an alternative which is what we use
in some instances.We also use assosiative arrays in javascript.

The fastest js-based method that I'm aware of is to have cf generate the
html for each set of options as js variables, then just set
select2.innerHTML to the one you want to use. Particularly efficient if
there are a bunch of options to set, since you don't have to iterate through
each one every
THis is slightly how one of the custome tags on dev exchange works if
I recall. One caution though, and this may or may not be a concern,
this method is bandwidth intense, as opposed to other methods.
Normally I wouldn't make a point of it except in my work place
bandwidth is a BIG concern and
innerHTML should be (in a perfect world) replaced by the dom methods,
but is still the fastest method to draw element on the browser canvas.
It has it's opposites however when drawing IMG elements, or any element
containing images. You might cause a denial of service attack on the
browser, but
The most bulletproof way to do this is to use QForms client server
gateway available here: http://www.pengoworks.com/workshop/js/gateway/
I have found that it is a lot better than the old twoselectsrelated
tag. However if you're using CF-7 I believe you can create it
directly.

Look for TwoSelectsRelated tag in the Exchange
I have used it in the past along with ThreeSelectsRelated

if you look on the dev exchange on MMs website there are a few custom
tags...are you looking for an MX or MX 7 solution though? That could
change the situation greatly :)

MX. Just installed MX 7 on another machine though. Will the solution to MX not
work on MX 7?

its more along the lines that in MX 7 you have some advanced
functionality with flash forms and and the ability to do some stuff
with actionscript.
