JavaScript ComboBox Needed

I need a simple Combo/List Box made in either a java applet, simple JavaScript, XML or whatever works. So I can add it to an html or php page. I need it to be able to have themes applied to it. You can see a working version I have attached to this project, I already have sample graphics made for it, and I just need it tied be together with a NEW JavaScript file to have same look and style use same graphics. I have a sample JavaScript that works you can look at, but the one I have attached in the zip file has too many features I do not need and it is a pay script, I need a simpler one, which is just for the look, I not need the extra features. Only the basic combo box to work with the templates I have included in the zip file. I Pay fast, and expect to be able to test the script to make sure it works and I need to see the code to make sure it is clean and not encoded. Should be simple, fast easy money, for someone..
