I'm trying to create an experience where the user fills out a form and then receives a custom product box based on their selections. I'd like the user to then be able to change the quantities of items in the box, if they choose to, before adding to cart.
Please let me know if there are any solutions for this type of set up.
Thanks in advance!
So, you want to implement this functionality on separate page? like user fill form and then on selection base you want to show theme product and use can add to cart directly form this page?
For that you have to do some custom code to do this.
