Today we are excited to announce that we are extending Divi Builder support for all custom post types, including automatic support for popular post types such as WooCommerce products, The Events Calendar events and more. This means that you can now enable the Divi Builder on any type of post and you will no longer be limited to standard Divi post types such as pages and projects.
