I created a page for product information for this collapse menu using additional content section on the left.
The problem is it shows this page on every product you click on
How do I make it so that each page is only visible for that product?
You’re using the “default” product page template (top of your screenshot) – which is what all products will use by default.
If you only want this extra info/content to show on specific products, then you would need to create a new product page template, add the extra info/content, and then assign it to the products that you want it shown on.

Does anyone know how I can achieve this?
