Sometimes you don’t want to show the “Notify me” widget on a specific product. For instance, you have products you're not planning in the future and you don't want to keep your customer waiting for it. On these occasions, do the following steps to make sure that the button is hidden on certain out-of-stock product pages:
From your Shopify admin, click on Apps and select Notify me!.
Select Advanced settings from the Back In Stock> Widget section
3. You'll see the "Hide the "Notify Me" button on specific products" option.
4. As shown in the screenshot, you need to add the “hide-notify-btn” tag on the products you don’t want to have a “Notify me” button. Go to the Products, choose the products you have in mind, click on More actions, and choose Add tags:
5. In the opened section, type hide-notify-btn and then press the Add "hide-notify-btn".
6. Click on Save!
Feel free to contact us if you need any help hiding the button.
