Add out-of-stock text message to select options in Add to Cart Form

introfini → changed the visibility of the branch cherry-pick-84c6a86a to hidden.

introfini → changed the visibility of the branch 8.x-1.x to hidden.

The merge request (MR) introduces this functionality.

To configure the desired message, follow these steps:

1. Navigate to /admin/commerce/config/stock/enforcement/settings.
2. Set the desired message for out-of-stock notifications.

With these settings updated, each product variation will now display an indication if it is out of stock.

Something like this is definitely needed. Otherwise, it will be too troublesome for the end user, and a CSS class should be added for styling in sites that use processed attributes.

Needing this functionality myself. I ran the branch and can fill out and save the new form field.

But when I load up a product page, the {{product.variations}} field doesn't appear, which loads the add to cart form. I also get this error:

The website encountered an unexpected error. Please try again later.
