I changed cart drawer codes a bit, added a drop down list for guest to choose. This list, however, can be bypassed if guests choose Shopify Pay, as they will go to checkout page directly.
I want to make this drop down list a mandatory field. How to do that?
The list is not about the product, but about the shipping. Here is the background:
-
All products will be shipped to customers directly
-
Each product is associated with a location (but not shipping to the location).
Shopify support said I cannot edit the checkout page.
Thanks.
