Mark ports as input/output port

Hi there,

This question is rather simple: Is there any way to mark a port as input or output for the layout.
We basically want the links to use the top or left port as input ports, and right or bottom as output ports.

I could not find any solution to this other then manually setting the from/to ports in a custom layout.

Thank in advance !

FYI: We are in conversation with ‘Jason Stewart’ about buying a GoJS license.

There are no limits on how the code can connect ports. However, the GraphObject.fromLinkable and toLinkable properties control whether the LinkingTool and RelinkingTool will allow the user to draw a link from or to a particular port. Read about link validation at: GoJS Validation -- Northwoods Software

Also, whether or not a port is “linkable” or has any other interactive permission restrictions has no effect on the diagram layout.
