On Boards, Lists help to group Cards together as part of a step in the workflow. You can freely create as many Lists on your Board to complete your workflow. Lists can be placed and moved anywhere along the workflow.
To add a new List to your Board, enter a title on the Empty List column, then click the +List button below. Repeat to add more lists to your board.
Note: The Empty List column always appears as the last list on the right. If you already have multiple lists created and you can't see the Empty List column, click the More Options icon on the top right of a list, then click Collapse List. Repeat the process on the other lists until you can see the empty List column.
Members of a board can add a list at any time.
