Squarespace is moving Product Additional Info into page sections

Squarespace has officially begun rolling out a major change to how Additional Info works on 7.1 sites. If you use custom code to style your product pages or have complex product layouts, you need to pay attention to this transition.

What’s Changing?

Additional Info removed from Product editor popup

Traditionally, you edited "Additional Info" inside the popup product editor. Now, it is moving directly onto the page.

  1. Automatic Conversion: Your existing Additional Info content has been automatically converted into a Classic Editor page section located at the bottom of your product details.

  2. In-Context Editing: To make changes, you now edit directly on the PDP. No more jumping back and forth into the product settings popup.

  3. The Limit: Currently, you are restricted to one Additional Info section. Attempting to add a second section will return an error.

  4. Classic Editor Only: For this phase, the section remains in the Classic Editor.

Breaking Change for custom code

This is the most important part for those of us using custom CSS or Javascript

  • The Old Way: Additional Info was a child of the product detail container.

  • The New Way: Additional Info is now a separate section entirely. It no longer sits inside the .product-detail parent.

  • The Grace Period: Squarespace has added a temporary class, .ProductItem-additional, to the new section's content wrapper. This will be removed in approximately 60 days.

How to Prepare

  1. Check your CSS: If your code looks like .product-detail .ProductItem-additional, it will break soon because they are no longer parent/child.

  2. Update Selectors: Shift your styling to target the section directly or use the new structure.
