Reply To: Custom JS for single product pages only

Hello,

You can add JS into the Theme Settings > Custom JS.

Please try Theme Presets and configure for the products you need, in this case it would not be applied for rest of the site: https://xtemos.com/docs-topic/how-to-set-different-header-for-specific-page/

If you have any questions please feel free to contact us.

Best Regards
