Product options - add to cart button

In previous versions of eshop, when a product has options in products page the add to cart button was present along with the quantity. Then when you pressed add to cart the system would take you to the product details page where you could choose the different product options. Now there is a view details button with no quantity present. Has something changed? Am i missing something in configuration?
thanks

Hi again Theo,

I already answered you via ticket system. Here is it again:

From the version 2.7.0, with products that have the required options, then we use View Details button on the products list instead of Add to Cart button because shopper must go to the product details page to choose required options before adding product to the cart.

Hope that this is useful.

Sincerely, Giang
