Is it possible to create a map dependency to a complete section instead of just to a different field?  

I would like to customize my leads layout so that when I choose a particular option in a field (ie - industry), it will open up a section relative to that particular industry.  I assume I would then need further mapping from lead to opportunity and eventually customer, but hope this can first be accomplished in the lead module.  Worse case, I can create different sections for the various industries and only use those that are relative.  However, then I will have a number of fields that are not relative and it will make the module too "busy".  

I have done this with a form builder application (www.formassembly.com) that I subscribe to and it works rather well.  Any information on how to accomplish this within Zoho will be greatly appreciated.

Thanks,
