add one more select field in a Drupal module

I am using uBrowser to browse stuff. You can find uBrowser here: [login to view URL] As you can see, the browser window has 2 select scroll subwindows. You click select1, then the result is displayed in select2. So the workflow is like: select1->select2 What I need now is to add one more select before select1, let's say it is select0. Now the workflow is like: select0->select1->select2, whereas the browse result of 0 is displayed in 1, and 1 in 2 after you click in 1. Number of items in select0 is typically less than 10. The deliverable should not change the external APIs, and taxonomy-based structure of the module. Modified CSS and/or js files should be included as well to make the view look good on both IE and Firefox. ## 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 Drupal, PHP/Mysql, Linux,
