Locating ports near custom node content elements

[konst-sh]

I'd like to have a nodes with some custom content: lets say for simplicity a vertical stack of <div> elements, some of which should be associated with the ports, and others should not. I can't seem to figure how do I archive that kind of port positioning. The port customization chapter of the docs says that node rendering is responsible for the port rendering - does it mean that I will need to manually calculate position of the node content sub elements and somehow locate ports?
