Actually, I just wrote something very like this just to see if I could. The goal in the exercise was to create dynamic lists that didn't require me to reload the page every time I needed an update. The algorithm is entirely in javascript, and works basically like this:
You have two arrays, we'll call them "a" and "b". "a" looks like this:
a[1] = "Color"
a[2] = "Size"
a[10] = "Red"
a[11] = "Green"
a[12] = "Blue"
a[20] = "Small"
a[21] = "Medium"
a[22] = "Large"
The numbering of "a" isn't significant...it's just how I like to keep them straight. Array "b" looks like this:
b[1] = [10,11,12]
b[2] = [20,21,22]
The whole purpose of the "b" array is to show the relationship between the categories and the options...category 1 gets options 10, 11, 12, and so on. You could, naturally, alter this to States/Counties.
In your form you have two empty select boxes, no options. Pre-load the first one with the categories (or states, in your case), then as the user clicks on an item it's ID determines which element of "b" is used, which determines which elements of "a" are used to build the options for the second list.
