Kanban Board: How to only show sub-tasks of parents shown?

[Miriam Grundig]

Dear All,
Even when I see all sub-tasks on a Kanban board. There is ONE thing that I would love to change (or maybe someone can hint me to a nice solution for this?).

When I only show Bugs in a KanBan board, selecting sub-tasks would be great to only show sub-tasks of those bugs. Same of course holds true for Epics and Stories.

Otherwise I do see sub-tasks to totally unrelated items... which assuming that sub-tasks are always this: a sub to something else, doesn't make much sense w/o seeing the item they are the sub to...
I would even go as far as to assume that that would be the default behavior expected when creating filters like that.

Filter used: project = X AND issuetype in (subTaskIssueTypes(), Bug)

Expected behavior: Bugs and their corresponding sub-tasks are shown

Actual: Bugs and ALL sub-tasks of the project are shown

Thanks and cheers,
Miriam

Hello Miriam,

You are going to want to look into the JQL Functions added in by ScriptRunner For Jira, that add in a subtaskOF() jql function detailed at the link below that I believe will accomplish what you are looking for:

• Adaptavist Scriptrunner: subtasksOf(Subquery)

Using this Function you could do something like:

issueFunction in subtasksOf("project = X AND issuetype = Bug")

Regards,
Earl

Thanks! That would probably help but we try to avoid using extensions for now. I might be coming back to this ;-)
