Sometimes it helps to break down a task into multiple smaller tasks. You can do that by clicking the subtasks icon. Once you’ve clicked on it, you see a new list appear.
Subtasks are similar to regular tasks – they have a title, an assignee, and due date field and they can have their own comments and attachments. Subtasks that are assigned to you appear in your ‘Tasks Assigned To Me’ list like every other task. But you will see the title or the parent task as an indicator that it’s a subtask. If the parent task is assigned to you, you will see its subtasks in the details bar when you click on the task title.
