How to set different designs for product and cart page?
Cart offers and product offers can have different designs, there are two layouts available: Modern layout and flatten layout.
To change the design of your cart offers or product offers, select the funnel placement on the top dropdown on the Design page.
Design for each page (cart page or product page) will apply for all funnels of that type. For example, all cart funnels (both upsell and cross sell offers) will have the same look.
