I'm trying to add a 'Build a Box' option as a product that allows the customer to build a custom 10 pack from drop down lists of our flavors. I've pretty much gotten there, but when you click on the product the customer has to expand the 'Full details' section to see where you choose your flavors. I've also made the flavor field required, but it still allows you to add the 'Build a Box' product to the cart if the customer doesn't expand the 'Full Details' section and does not choose any flavors at all. Does this make sense? I think what I'm trying to do is make it so the 'Full details' section is never collapsed. Any help would be so appreciated!
