I have put the status of my epic into "Done" and they have disappeared from the backlog but not from my roadmap. Which means I have a list of 20 epics in my roadmap that are just sitting in done since February.
I don't want to delete them as I want to keep the Jira data, I simply just want to archive them like you can with Issues.
Some issues aren't completed - but I don't want to remove those from the epic I just want everything (even if it's in progress/to-do/incompleted in that month) for it to disappear and be archived.
