When you have a group of tasks, once in a while you might need to ungroup them. Whether it's changing tasks within task group or you simply want to make your Project Plan flat, ungroup the tasks:
- Open the task group.
- Drag tasks from the group to the main canvas.
- Close the task group.
- Right-click with the mouse and choose Convert to Task.
Voila! The tasks are ungrouped and ready for further modifications.
