Subtask is enabled but not selectable when creating an issue

[Tom Elfers]

In my JIRA project, I created Epics and Tasks, and can set a task parent to an epic. I originally deleted the Subtask type, but re-added it in Project Settings. When I create a new task, the Subtask type is not listed in the Issue type pull-down. Task, Epic, Story, Bug are there but not Subtask. I have way less than 500 issues in this project so that should be ok. Any ideas?

Ok, found another, maybe only, method to do it: "Add a child issue" from an existing Story, Task or Bug. Guess they didn't want you freely to enter a issue type and Parent, then sanity check it upon saving to be legit or not.

Sub-tasks are fragments of an existing story, and hence have to be created from within the story.

It would be a poor UX to have it on the create option.  The process would have to be

1. Create issue
2. Select a sub-task issue type
3. New field appears asking for the containing issue
4. User would need to know the issue key that the new sub-task is part of

Of course, the new field should be search enabled, but even that becomes a pain to code for and use.  One example - "Why can't I add a technical-task for ABC-123? Why can't I find ABC-123 in the search?".  Because project ABC does not have the technical-task type available.  

It's not that they don't want you to freely enter it, it's that doing it that way is complex, finicky, counter-intuitive and slow (and would mean a lot more code for the create process)

Hi @Tom Elfers  Welcome to Atlassian Community!

Sub-task issue type is not visible on Create issue screen. 

After issue creation, you can create a new sub-task for a Task issue type.

You can create Sub-tasks in bulk using CSV import or via API. 

Previously, if you had sub-task issue type in your project and removed sub-task issue type, then where you moved the sub-task issues, without moving issue to another issue type, you can't remove issue type from Project issue type scheme.

Thanks

That's weird - your "Create subtask" option shown looks different from mine:

Yes - though, this works! Thanks!

@Tom Elfers It's the same. In my screenshot I am at Task issue type. While in your screenshot you are at Epic issue type. For Epic issue type, Jira shows "Add a child issue" and  for issue type below Epic it show "Create Subtask"

Ahh, of course! All context sensitive.
