We are looking to move the Gravity forms product add-ons to the Cart Page rather than the Product page? We'd like the customer to add the item into their cart as quickly as possible and then select their options while in the Cart.
When submitting the product (adding it to cart) the form data is pulled and posted on the cart. Options update, price updates if needed etc. The issue with moving that form to the cart page is we would have no way of updating the information from the added options.
This should be accomplished with the use of AJAX and some good custom code.
