Divi’s loop builder supports custom fields created using Advanced Custom Fields (ACF). When selecting a custom field, you’ll find all ACF fields at the top, which are labeled with their associated field names.
Enable the Loop Element option on any module.
Use the Dynamic Content option
on the looped element's body or title field and choose the Loop Post Custom Field option.
Open the Select Custom Field dropdown.
Select the ACF field to be used.
Click on the Apply button.
