By default, after adding an item to the cart, the customer cannot change its parameters, unless he removes this product from his cart and adds it to his cart again with new parameters. If the product has many options, it will be difficult for the customer. The Modify Cart Product Parameters extension allows a customer to modify the parameters of a product in their cart. The extension adds a new button for products with options in the cart headers (mini cart) and on the cart page that allows them to edit options for that product.
