How to layout nodes without links

In my application I have a bunch of JGoNodes that are not linked. Because of this, the JGo Layout manager just lays them all out into a straight line. I need them to wrap around such that they fill the entire view. While I can use the zoomToFit() method to show all the JGoNode objects I would like to take up as much vertical real estate as possible before doing this.
Is there a way to configure the JGo Layout managers to perform this operation? Thanks!

No, there isn’t. I recommend removing such nodes from the JGoNetwork manually, before calling performLayout(), and afterwards positioning them in a tabular format as you see fit.
