On our shop we sell clothing. When products are sold out we want to show them as "back soon" on the POP. People can use the "product alert" to subscribe for a back in stock notification.
Idea: For our product (clothing) we use the attribute "Size" e.g.: XS, S, M, L. We want customers to be able to filter on these sizes when browsing our catalogue. However, when filtering on a Size, Magento shows all products for which this attribute is applicable. Regardless whether on stock or not. Therefore it can be the case that when using this filter as a customer, you click on the results and on the PDP of this product you see this size is actually not on stock.
As a merchant I would like Magento to provide filter results considering the actual stock level and only show results of products who have positive stock for this attribute.
I know that a solution can be to hide products from the POP when they are out of stock, but then we cannot use the "re-stock alert" function.
