Hide Out-of-Stock Products in WooCommerce

If we want to hide out-of-stock products from our store pages, we need to enable the following option in WooCommerce, Settings, Products tab, Inventory, and turn on the Hide out-of-stock items from the catalog option.

We recommend not hiding them, but instead using a plugin such as Back in stock notifier, or Shoptimizer's native functionality, so that your customers can subscribe to receive a notification as soon as the product they are interested in is back in stock.
