Level ID - This setting determines which level of the tree the records you have selected from the search will appear on.
Level Records - Beginning from the previous level (which is automatically set as the starting point for your search), search for a set of related records you wish to display on this level of the tree.
Recurring Level - Enable this setting to allow this level to repeat itself as long as there is additional data that satisfies the query. This is useful for data structures that could be infinitely nested (e.g. Tasks to Sub-Tasks).
