Sticky product images in Multi Shop
Would you like to make the product image sticky so the client could read about your product and take a look at it too?
Just go to Appearance > Customize > Shop and use the option Sticky product image at the top of the menu panel.
Sticky links to previous and next products
In the same menu, you can check the Enable sticky links to previous/next product option. This will add sticky “Previous product” and “Next product” buttons to your product page, so a viewer can easily browse your products.
