Why are specific products or collections not showing up in my Wix Online Store?
If you have set up an inventory for your Online Store, your products will automatically be hidden from your site when the inventory for this product reaches zero. This would also cause collections to be hidden if the inventory is empty.
To add to the inventory of a specific product: Click your Product Gallery to select it > click Manage Store > click a product to open Product Details.
Under Options and Inventory, check the box next to I want to manage inventory > next to Number of items in stock, enter the number of items.
Important: If you have multiple product options (i.e., you have checked the box next to I want to add product options like size and color), after checking the box next to I want to manage inventory, click the Manage Options and Inventory button > edit the number of items in stock > click Done.
