Can I hide the Back in Stock button for certain products?
Yes! The easiest way to hide the button for a product is to add a tag bis-hidden to the product using the Shopify admin.
If you're not sure how to add a tag to a product take a look at Add tags to products in the Shopify manual.
This tag will work with buttons added via the Back in Stock storefront widget. It won't hide custom buttons or forms added to the product template. For an example on how to hide a custom button or form in your template see our developer section.
