Scroll down to see the layout built using a page builder. If you would like to rebuild entire product page with a page builder, we recommend using Beaver Themer – this theme is fully compatible with the plugin.
There is no page builder used to build this product layout. It's simply using the default theme layouts and styles.
There is no product description here. Also no attributes are set to display. But reviews are enabled as you can see below. So, this is how a product page looks with no tabs.
You can easily disable the Intro section for any product. This can be done either with a page template (or should I say a “post type template”) or with a dedicated custom field.
