Agent form for car showroom

Agent form for car showroom

Hey all!

I am trying to make a useful crm form in creator for a car showroom. However, I am struggling with the best way to configure the CRM modules so I can make the form useable. 

They need to be able to have say a basic top level of is it a drop down for a car or a van, then maybe a drop down for a type of car/van e.g. suv. But where it is becoming complicated for me is the things like engine size.... if someone is looking for a 3l suv by BMW, but might be open to a 4l - what is the best way to configure this in the crm? I have a lot of these elements in the space like paint color etc. So its not just one and when looking at creating a subform its limited to 2 per module, and modules are limited and im sure i will run out. 

I will then need to pull this into my creator form, which I have the basic elements done, but the subforms etc or the way to configure the more complicated (potentially thousands of combos.....) just dont know best way to do it

any advice appreciated y'all! 

thx
