Subtasks
========

Subtasks are useful to split the work of a task.

Each subtask:

- Can be assigned to a project member
- Have 3 different statuses: **Todo**, **In progress**, **Done**
- Have time tracking information: **time spent** and **time estimated**
- Be ordered by position

Creating subtasks
-----------------

From the task view, on left sidebar click on **Add a subtask**:

You can also add quickly a subtask by entering only the title:

Change subtask status
---------------------

When you click on the subtask title the status change:

![Subtask in progress](http://kanboard.net/screenshots/documentation/subtask-status-inprogress.png)

The icon before the title is updated according to the status.

![Subtask done](http://kanboard.net/screenshots/documentation/subtask-status-done.png)

Note: When the task is closed, all subtasks are changed to the status **Done**.

Subtask timer
-------------

Each time a subtask is in progress, the timer is also started. The timer can be started and stopped at any time.

The timer records the time spent on the subtask automatically. You can also change manually the value of the time spent field when you edit a subtask.

The time calculated is rounded to the nearest quarter. This information is recorded in a separate table.

The task time spent is updated automatically according to the sum of all subtasks time spent.
