If I drag a parent (say Feature) in Kanban board (say from Open Status to closed Status), then the status of its childs (say User stories) is not changed.
Similarly if I drag all childs (say User Stories) in Kanban board (say from Open Status to closed Status), then the status of its parent (say Feature) is not changed.
Is this the expected behavior? Please throw some light?
This is the correct phenomenon for now. You can use some third-party extension to achieve this for a workaround.
And there has been a feature request in UserVoice, you can also vote up for it:
