ASP.NET Dropdown Menu

I need an ASP.NET menu similar to the JavaScript menu on this site. [login to view URL] The problem is that JavaScript menu's do not pop over an ASP.NET combobox control. The solution must have a menu with a combobox below it to demonstrate the solution to this problem. The menu should be in the form of a user control if possible, but this is not absolutely required. Underlying code must be C#. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Windows, ASP.NET, C#
