Hi,

I need a product package page with a few options.
Is there any similar contributions? Or where shold I start to do the coding.
Appreciated if anyone can give me some simple steps or direction.

Computer Systems
- system 1
- system 2
- system 3

After click, it'll show pre-config componets and some of item with optional upgrade(like upgrade from 256M to 512M).

Thanks
ERIC
