I'm working on a store that wants additional customization options + charges for products. we can add the customization option as like in the URL - https://help.shopify.com/en/themes/customization/products/features/get-customization-information-for.... However, we want to add extra cost to products when customers choose different options.
You can check the below app, which has a similar feature we want. The product customizations add a separate line item in the checkout, which is no present in the cart. How is this possible, or is there any workaround?
