Make it easy for visitors to adjust the product quantity at various stages of their shopping experience.
Enabling product quantity
In order to enable the product quantity selector, head into Shop -> Settings -> Product quantity selection and tick the box.
With the box ticked, all your product pages will show the option for visitors to modify the quantity they want to add to their cart, either by clicking the + and - buttons or typing in a number in the field. If a visitor hovers with their mouse on the quantity input field, they can see how many items are left in stock. On the checkout page, + and - buttons are also added to each product on the cart overview.
If the product quantity selection box is not ticked, the quantity selector will not show on your product pages, and the + and - buttons won't show on the checkout page.
