Hi Dima,
Thanks for replying. The problem is that when I open the force sell for edit, a customer can remove it from the cart. I dont want it removed. It must be part of the main product. For example, Am selling a computer and I need the customer to buy another service along with it. This other service must have a quantity of 1 regardless of the increase in the quantity in the main product.
Maybe to explain a little more, look at this screenshot: https://prnt.sc/tf4kv8
The main product is platinum PCI Plan and the forced sell is the registration fee. This registration fee should not be removed from the cart for as long as the main product is in the cart. And a the same time this registration fee must not be more than 1 quantity even if a customer buys 100 quantities of the main product.
I hope this explains in details.
