I need a customizable field for a product in Drupal 8 drupal-commerce. I succeeded to add such field through an order item type. But if I want to add several same products on cart, this field stand uniq for all the products.
How can I have a line in cart by same product with the specific value of the customizable field for each one (I'd like to avoid the creation of a product variation by specific value. This specific value is customizable and so not in a finite set) ?
Thank you very much for your help.
