I am trying to create a website where customers can buy a set of spices which consists of 12 spices they choose from a list. Since the spice set consists of 12 different spices I would like to cap the maximum number of options checked at one time to 12 and also connect the checklist to a product of each spice on its own(ex: a product for cumin). Currently I am using agile bundle builder and have created a checklist with this app, but I have no idea how to customize this checklist to have a maximum of 12 options checked at a time. How should I go about doing this and what apps should I use to get this done? Thanks in advance.
