Widget enabled on sold-out variants?

If the toggle is off, customers will not see any purchasing options when the product is sold out.

The product page will simply indicate that the item is unavailable. (See example below)

If the toggle is on, customers will still see all purchasing options — just like they would for a product in stock.

This can be useful if you want to allow pre-orders and subscriptions or keep interest in a product that will be restocked soon. (See example below)
