ASP.net MVC and JQuery Cascading Dropdown list

Imagine that you have an E-Commerce site and you would like the user to drill down into the attributes of a product to help the user find exactly what they need. You display a dropdown list of product colors. Each time a user selects a new color, a dropdown list displaying products available in that color is populated. In this demo, I've created a small application demonstrating on how to use ASP.net MVC 1.0 framework and JQuery to complete the task.
