Hey there!

Thanks for reaching out on the Community. When you click on the border of your swim lane a panel should appear to the side. This panel will allow you to adjust the number or direction of your swim lanes.

To add or remove lanes change the number of lanes listed in the panel.

To change lane or label orientation select “Vertical” or “Horizontal” from the drop-down lists in the panel. When you reorient a lane all objects in the lane will reorient as well.

To move a lane right-click on the border or header of the lane. Select “Move Lane Up” “Move Lane Down” “Move Lane to Left” or “Move Lane to Right” depending on your desired direction.

I hope this helps! However if these steps don't work it may be document-specific so shoot us an email over to support@lucidchart.com with the url of your document so that we can take a closer look :)
