In this article, you will learn about the creation of a subtask.
Subtasks can be created inside the project Gantt view by clicking on a task and then keeping the left mouse button clicked, dragging, and dropping it on another task will convert it into a subtask.
As soon as you create subtasks a drop-down icon (arrow) will start appearing on the left side of the parent task.
Click on it and the subtasks will become invisible to provide you an overview of parent tasks only.
Your subtask has been created.
