Hierarchical lists Hierarchical lists allow users to view records from related lists directly from a v2 list without navigating to a form. Note: Hierarchical lists are not supported in List v3. Tables that have hierarchical lists enabled always display in List v2. Lists can have sublists in a hierarchy that can also be accessed in list view. To expand or collapse the related lists on a record in a hierarchical list, click the arrow () beside the reference icon. Figure 1. Hierarchical list Administrators can enable hierarchical lists for a table. For more information, see Enable a hierarchical list.
