I am working on small webshop with just 5 products but i need one additional product to be mandatory (and the user needs to select a variation on it.)
For example, user adds to cart products A and B, but before he can check out, he needs to select an option from mandatory product (variable product) before he can proceed. Without it he cant check out.
How could something like this be done?
