This plugin makes it possible for you to display any of your custom post types using the blog module. The blog module only allows you to display built-in post types. This meant that you couldn’t display or style your custom post types using Divi’s page builder.
Divi Custom Post Types changes all of that. Once you have bought and installed Divi Custom Post Types on your site, you will find a brand new module in your Divi builder with all of your Custom Post Types. All you have to do is select the ones you want to display and style it up how you want to.
