Use subtasks to break up the work of a task into smaller parts or to help divide up the work among multiple people. Subtasks function like independent tasks with all the same fields as a parent task, but are embedded within a parent task.
To create a subtask:
Click the subtask's title.
When viewing a subtask's details, notice the parent task's name appears above the subtask's name. Click the parent task’s name near the top of the task details pane to return to the parent task’s details.
Completing a parent task will not complete the subtasks within it, they will need to be completed separately and will remain greyed out within the parent task when completed.
You can easily identify if a task has subtasks along different views and features in Asana, like boards, calendar or workload. Look for the subtask count icon next to the name of a task.
The list view allows project teams to display projects organized in a layout that make it possible for users to quickly understand what's left to be done in the project at a glance. Teams can see a snapshot of timelines, critical paths, approval status, task durations, milestones, dependencies, subtasks and more.
Subtasks also appear on the list and are best used in instances where a project moves at different levels.
Asana users can set field values, including custom fields, on subtasks and collapse and expand subtasks for the bigger picture or the minutia.
By breaking down a massive project into more manageable parts, users feel confident in successful project completion.
This visual list showing subtasks helps to identify bottlenecks, potential issues and inefficiencies, at a glance.
You can see subtasks in your timeline view, allowing you to have a global view of your projects. Learn more about how subtasks work in timeline view here.
Subtask and project association
You can manually add a subtask to a project if you want it to appear in your project's task list, project calendar and project timeline along your other tasks. You can also specify an assignee, as subtasks do not inherit it from their parent tasks.
Press Tab+P on your keyboard to focus on the subtask’s project field.
Note
The subtask will also be reflected in the project's files, progress, and calendar views.
Subtasks are visible to anyone who can see the parent task. Learn more about task permissions.
If you'd like to add custom fields to a subtask, the subtask must first be manually added to a project.
You can also do the reverse to convert a subtask to a task.
Note
You cannot drag a parent task into its own subtasks.
To view subtasks associated with your parent tasks, click on the black triangle icon from your project's list view.
In list view, you can expand or collapse all first level subtasks in one click. Open the Options menu on the right side of the project toolbar and choose Expanded or Collapsed beside Subtasks.
Only the first level of subtasks is affected. Deeper subtasks stay collapsed.
