CSS Display Function

We have a small project that we need some assistance with. We have a large list of menu items written in ASP that is driven from 2 tables from a MS Access database. The list has an upper level section (derived from the first table) and multiple items associated below each upper level section (derived from the second table). We need a show/hide function added on the upper level section to show/hide the multiple items underneath each section. I believe the best method to do this is with CSS/Javascript but I am open to suggestions for alternative methods. ## 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.
