Hi all,
I need to get products organized in a tree, so that I can set up some services only if the "main" service has been subscribed (for example, in car renting, you can choose the air conditioner only if you rent the more expensive model...it's just an example!).

Moreover, I need to set up periodical (weekly, monthly, daily) costs for each product (again, think about the car renting service, just as an example).

Is there away to get this with Sugar? Maybe I need some optional modules?


Thanks in advance.
