CascadingDropDown is a jquery plugin that allows you to create cascading drop downs that depends on ajax to get the data. This plugin was created as an update to Raj Kaimal's CascadingDropDown jQuery plugin for ASP.NET MVC. Updates include support of dynamic drop downs. I will be updating this soon with features such as templating the dropdown list, etc.
Visual Studio users can install this directly into their .NET projects by executing the following command in the Package Manager Console
PM> Install-Package CascadingDropDown
