Need Arrows for the attached image.

[sarvweb]

Hi Support, I need an help in treant js example that i have created.

Kindly see the attached image which is showing red and green connector line. I have created script for the connector to parent node to other parent node child or vice versa. But the problem is in the red and green connector line, the arrows are not coming like you can see grey arrow in other connector line.

Plz give me solution for this so that i can create the start and end point arrows in red and green line.
