Using Custom Fields | YOOtheme Documentation (WordPress)

YOOtheme Pro supports custom fields created with the Advanced Custom Fields or the Toolset plugin. It can load custom fields from a Page, Post, Category, Tag and User as well as any custom post type and taxonomy. Custom fields which contain a single item are available for mapping together with the default content fields and are grouped under the field group name. On the other hand, custom fields with multiple items have to be selected under the Multiple Items Source option. They are grouped under the field group name.
