Update description

Client would like to show subtasks as a drop down list in card on Kanban Board, similar to how it is currently done in a Work Management board.

Currently, while you can add subtasks to cards on a Kanban board, it will only show a listing of the subtask issue keys associated with the issue, without an ability to click on them and get additional information. Client would like it to be more like Work Management where you can click on a marker and get a drop down listing of the subtasks with links and subjects. Screenshot of JWM board:
