Click on a task inside your task list
Click on the “Add new subtask” button to add your subtask. A subtask is a smaller task within a bigger task or project. It helps to complete the main task or goal.
In this example I added a subtask for the task Facebook/Instagram Ads. What are steps needed to complete that task? Those steps will be your subtask.
You can add as many subtasks as you like. For a project member to mark a task as complete, each subtask beneath it must be finished first.
