Magento2 Out of Stock Assosiated Products not showing in the dropdown options for Configurable Products

问题

I am facing an issue with Magento2 and I am not sure whether it's a bug or not. I want to show Out of Stock Assosiated Products in the Configurable Product Dropdown.

In the admin settings, Stores -> Configuration -> Catalog -> Inventory -> Display out of stock products, this is already set to "Yes" but no luck.

I have tried several modules with integrating plugins and did a lot of research on this but could not find any solution for this.

Lets take an example - I have a Configurable Product with Child products Size - S , M , L and for instance L is out of stock. So currently I am able to see S and M in the dropdown options for my configurable product.

I want to see all the 3 Child products with the mark of "Out of Stock" like L - Out of Stock or something like that.

sorry for the late reply. I was really busy with different projects.

So for this, i used 1 module and did customized that based on my requirements. I am providing you all the files and folders so anyone who needs this, can upload the files.

Created a module - Jworks/ConfigurableProduct so the folder structure will be /app/code/Jworks/ConfigurableProduct

Create a file app/code/Jworks/ConfigurableProduct/registration.php and enter below code -

            $subject->setData('allow_products', $products);
        }

        return [];
    }

}

And after all these, you can run all the commands for installing the Magento2 extension.

I hope anybody can get help with this.
