Special Links in TreeLayout

Hello. As the img.

1.How can I draw a link from CEO to level 4 with a Orthogonal cartesian line like the red one ?

2.The Node which is Named ‘level4’ it Y-coordinate should equals the Node Whose ID is 7.

Look forward to your reply. Thankyou.

It is possible to customize TreeLayout so that you can control which layer each node belongs in. Here is an example that also implements different “bands” using Groups.

Note however, that the LayeredTreeLayout defined in that sample was only implemented to work with TreeLayout.angle being zero, not 90 as you show in your screenshot.
