Problem

Currently, when we search using any standard issue key on the board, only the particular issue is displayed, not the child issues/subtasks linked to it. 

For example, if a Story has 3 subtasks linked to it, when searching the issue key of the story, the story is visible on the board and not its subtasks

Suggested Solution

We should be able to display a particular parent along with its child issues on the board. 

Why This Is Important

It will be easy to fetch the child issues of a particular parent on board rather than switching to advanced search. 

Workaround

Use the following JQL in the advanced search to fetch the child issues of a parent: 

project = "ABC" AND parent = ABC-123 ORDER BY created DESC
