Under this new sorting option for the list view, you would see all the parent tasks with their respective subtasks in an indented list under it. Though in this new sorted view, we would not see the sections but still be able to see the custom fields assigned. This is because a parent task’s subtasks are often in multiple sections.
In this example, the task labeled P would be the parent task. The tasks labeled S1 are direct subtasks of P. S2 would be the subtask of S1 (sub subtask).
