Hello, @Chee,
Thank you for your inquiry. We would like to inform you that it is not possible to directly edit any of the archive pages (Blog, Shop, Category, Cart, Checkout, etc.) with any of the page builders.
These archive pages can only be rendered using Theme Settings or with the Pro plugin.
However, you can check and set all available settings as per your requirements under XStore > Theme Options > WooCommerce >> Cart/Checkout Layout.
To display the WooCommerce checkout form on a custom page using a shortcode, you can use the following shortcode:
[woocommerce_checkout]
By adding this shortcode to any page or post content, it will generate and display the WooCommerce checkout form. Users can then fill in their billing and shipping details, choose a payment method, and complete the purchase.
Best Regards,
8Theme’s Team
