Top Custom Panel Menu drop downs

Hi all

I am building another CS Cart website, and I wanted to use a top menu. Thing is, I have lots of products. I can split these down to say 9 groups.

Has anyone managed to build a working emenu that can run bug free with CS Cart 2.1.4? I realise it might mean I will have to add the code into a html box, but the big challenge may be to get it to lay over the top of other content in CS, i.e. as a layer.

I have had problems before with layers in CS, they don’t seem to work.

Any ideas or examples out there?
