I have cart widget on the right side with individual item, I would like to mix all of the individual item into one Mix item when 'Mix' button is call with 'Mix name' input field like in the picture:
So Before 'mix',
Every product in the cart is an Individual product the cart will detect item and restriction for item that belong to which category - so based on restriction, only max 9 items can be in the cart at this time.
when user hit mix:
every individual product in the cart will merge into 1 Mix product with including product name for each, product quantity for each, product price total
