Is there a way to make user story a subtask of an task?

Question

I would like to make following hierarchy:

Task
   -subtask
      -user story 
      -user story 
   -subtask
      -user story 
      -user story 

But when I am trying to add user story as a subtask to existing task it is not possible

Answer 1

No, it's not possible the way you want.

I suggest the most common approach and that's to use Epic -> Task/Story -> Sub-Task hierarchy.

Epic
  - Task or Story
      - Sub-Task

The Sub-Task is the smallest task in Jira and it doesn't make sense to have any further sub-issues. Moreover, (User) Story is bigger piece of delivery than a Sub-Task. Common Tasks and Stories are usually equivalent issues (at the same level) and just used for different type of task.

Answer 2

Jira only supports a three level hierarchy with Epic at the top and sub-task at the bottom.

You can use links though. For example you could have a sub-task linked to a number of stories. The linked stories would be visible in the sub-task.
