How do you remove subtasks from a Kanban board once its parent story is not on the board?

[Steven Zeck]

On a Kanban board, I have the board sub-filter as the default fixVersion in unreleasedVersions() OR fixVersion is EMPTY, which I like because we follow a two-week release cycle, and issues don't stay on the board longer than that. However, I'm finding that sub-tasks are staying on the board, despite its parent story being done and released and no longer on the board.

One way to fix this would be to add the Fix Version on the sub-task, but I don't want to clutter the Release Details screen with them. Another looks to be adjusting the filter query to be something like: project = PROJ AND (issueType in(Epic, Story, Bug, Task) OR (issueType = Sub-task AND statusCategory != Done)) ORDER BY Rank ASC, but that looks to do some weird things to the board, one thing being that the Create issue button no longer displays under each column. Seeing what other issues it causes.

Is there any other solution out there? I assume that they will disappear from the board after 2 weeks, which is what I have the Completed issues time frame set to on the board settings. Is there a way to "force" that?

Hi @Steven Zeck 

Thanks for reaching out to the community, As my understanding subtasks should not be shown in Kanban Board is that right?

solution: In configure Board---->Quick filters there you can set JQL.

No, I want subtasks to show on the Kanban board. However, when its parent story is no longer on the board, then the subtask should also no longer be on the board. But they are in the scenario I outlined.
