[Catalyst] Generate dynamic list

[Danny Warren]

It would have to be done with javascript no matter what framework 
(unless you wanted to do it with multiple partial form-submits, which is 
kinda ugly and you would end up using javascript anyhow to smooth out 
the submits most likely).

This is usually called "select chaining", and I remember seeing some 
article that was catalyst-centric floating somewhere.

Ah, here we go (haven't used this method myself, not sure how right this 
article is, but should get you started):

However, I think the consensus around here is not to use the Prototype 
plugins or helper, since they really shouldn't be plugins in the first 
place (and locks you in to whatever version is in the HTML::Prototype 
module).

I just insclude the prototype.js script directly in my html template 
whenever I need to use prototype.  More info:
