how do I add an existing issue to an epic?

[Meredith Volk]

I found a doc that mentions using "Plan mode" but I don't see this as an option in my board. Presumably that's because I don't have permission to access Plan mode. Is that the case? Or is the doc just missing some steps?

This simple core task is clearly painfully difficult to find and still annoying to use. It's truly staggering how Atlassian consistently botches UI by burying key features. Noisy interfaces poorly prioritized.

Figured it out from these steps

This is the best answer, that actually worked

Hi @Meredith Volk,

Are you using a Scrum Board or a Kanban Board?

In Scrum Board mode you can choose to show the Epic panel in the board configuration,and Match existing Issue and Epic by dragging cards.

I'm using a Kanban board but I think I figured it out! We have a custom field called Epic Link on issues. I can type the epic in there and link it that way.

[Ollie Guan_携程_]

That's true, it can also be implemented through Epic Link.

[Guido Zardo]

In case the Epic Link was not showing you can unhide it in the issue layout settings

Love the drag-and-drop method for Staged issues, but if something is not Staged it does not show up in the Backlog and you can't drag it into the Epics panel so oh well! 

How about making it easier to link a task in progress to an epic?

As of 2021:
-> Open Story
-> Click the 3 dots

-> Choose "See the old view" at the very bottom

-> There is now an "Edit" button at the top of your story

-> It has a field "Epic - Link"

-> Choose your Epic

Thank god for this response. Worked! Super easy. 

I was using the "new"(?) view which had the "Epic Link" field but it would it wouldn't let me edit it like it allows in the "old view." Bizarre to say the least. Thanks for the work around, saved my day/night!

Easiest way is to go the issue and `link the epic using `link-issues` to it by selecting `Created by` in the drop-down.

[Tracy Kabeshita]

I attempted this and it only "links" them, it doesn't make them Epic issues.  I selected "relates to" as the way to link them.

This is what I would like to see:
