Subtasks are created when there is a need to branch out a stage to more than just tasks.
The first step is to click on the task. A side bar will appear.
The next step is to click on the “+” icon in the top right corner.
From the list that appears choose “Subtasks”.
To add a new subtask, click on the “ADD NEW SUBTASK” field and write the name of the subtask. When you are done, press enter and your subtask will be saved.
While subtasks are not as complex as tasks, we can still add a due date and person responsible if needed.
