Drill Down Timeline PRO aggregates all datetime values in your Date Value (X-Axis) field and creates a drill down hierarchy. You can use the toggles in this section to select which time units are used as drill down levels that can be accessed by the user. This section will display all units that you have added to the Date Hierarchy field.

All the enabled display units will be used as drill down levels in descending order. For example, if you have enabled Days and Months, the user can click on a specific month and the visual will reveal data for each day within that month.
