I am new to yED and I need help creating my own nodes or shapes. I thought I could use groups to do this, like in Word. But when I try to use the automatic layout feature, my groups become a disaster. This obviously isn't how groups are intended to be used. I'm having trouble understanding them because it seems hard to manipulate them as a single object and I expected them to behave as a single object.
How can I create custom nodes or shapes?
