Hi, possible to implement similar functionality?
When you click on the button “Add To cart” to add one item to the cart (as default) then the button disappears and a box appears with amount of this item in your shopping cart and buttons “Plus” and “Minus”. When pressing “Plus” or “Minus” product added to basket or diminished. It should work without reloading the page. When you refresh the page, the products that are already in the basket should be actively box with buttons plus, minus.
