WooCommerce Quick View allows customers to easily view products and add them to their cart from a lightbox, even if they come with variations.
If you install the quick view plugin, a ‘quick view’ button will be added to product loops. Clicking on this button will open a lightbox, allowing you to see product details and add them to your cart.
You can choose to display a ‘quick view’ button in your loop or set non-ajax add to cart buttons to open the lightbox on click. This is particularly useful for showing variation details.
