How do I organize kanban board with an Epic swimlane and Subtasks grouped under a Task/Story?

[Filipe Teixeira]

Hi great Atlassian community!

I would likt to know how can I display Subtasks under its respective parent Task or Story while using Epics as swimlanes.

Please check the screenshot of what I want to achieve below and the screenshot of what I do not want.

1. Good example

As you see, here the subtasks are under their parent Task. I understand that some times I will have a sub-task in the To Do column which is the child of a Task that is in Progress, but this case is unavoidable. However, I want to avoid the bad example which is depicted below.

2. Bad example

As you see, here we have Subtask of Task 1 under Task 2. Instead of under Task 1. This is not what I intend. I want Subtask of Task 1 to be displayed under Task 1.

The query that I am currently using is as follows:

project = "myProject" ORDER BY issuetype DESC, Rank DESC

Let me know if there is a function out there to be added to the above filter and help me group the subtasks under its respective task.

Thanks in advance for your help!
