How to include subtasks in board from filter

[Mateusz Gruszczyński]

I've created scrum board from existing filter but number of tickets in board is smaller than in filter result. Turns out that tasks that match filter but are sub-tasks of tasks that are not matching my filter are ignored in a scrum backlog. Is there any way to add those sub-tasks to board without adding parent tasks?

No, Jira ignores them in the backlog because they are not a lot of use.  You can't rank them (as it's nonsense), so Jira simplifies by showing you only the issues you can rank.
