Transforming a "Subtask" in to a "Task" of a Task List.

Transforming a "Subtask" in to a "Task" of a Task List.

Hi all !

I'm using the free edition of Zoho Project.

I created my task list, under this, I created some main tasks and under these main tasks, I created subtasks.

The problem is in the Kanban view... the subtasks are not there.... 

So, I'm trying to change my subtask to a tasks.... but the I did not find option to do that in free edition....


Is there any configuration to enable it? Or, We have to upgrade the version to have this feature?

Rgds, M
