I read this , but when I copied the code into my own project and followed the documentation, this just didn't work. The node size and the group size are weird. No matter how I tried to edit the css settings, the height of the node just wouldn't change. Can anybody help me?
And btw I also want to ask, what do .rocItem and .rocItemContent mean? When I use my browser's inspect function, I also see a .rocItemTemplate, what is that?
