Hi, how i can add simple but very important function for quantity selection on product cart in grid? not only in product page. This feature is very simple, helpful and fastener shopping method, when not require see product page but only price, title and photo.
Sorry, but there is no such option in our theme and WooCommerce by default. It may require additional code customization or extra plugin but we don’t have an instruction for this. It is out of our theme support scope.
Try to disable AJAX add to cart option in Theme Settings -> Product page. Then it should work with a standard WooCommerce add to cart function and quantity buttons will work correctly as well.
