Plan big, then execute on the details. Break big, overwhelming tasks into small, manageable sub-tasks.

In Todoist, you can even break down those sub-tasks into smaller ones. Learn how to create a sub-task, convert a parent task into a sub-task, and more.

  3. Drag the sub-task above or below its parent task, and to the left of the task list.

Use task hierarchies to organize your task lists into sections with headers.

Noteworthy

  • You can only create sub-tasks in a project. If you're viewing tasks in the Today view, Upcoming view, filters, or labels, open the parent task in the task view and create the sub-task.
  • Todoist supports four indent levels. For example, a sub-task is using indent level 1 and a sub-sub-sub-sub-task is using indent level 4.
  • The indent of a task can't be changed when working in the task view.

FAQ

Why do I see sub-tasks twice in my Today view?

If you set the date for the parent task and the sub-task to today, they will both show up in your Today view – meaning your sub-task will show up in your Today view twice. This is something we're evaluating for usability.

Is there a way to view a task's completed sub-tasks?

Absolutely. You can easily see a task's completed sub-tasks using the task view.

Can I use drag and drop to turn a task into a sub-task while in board layout?

No, unfortunately not. You will have to be in list layout if you want to use drag and drop to turn a task into a sub-task.

I'm using a sorting option, but my sub-tasks aren't sorted in task view. Is this a bug?

No, this is expected behaviour. However, please note that you can use drag and drop to manually sort your sub-tasks while in task view.
