Multiple connections to/from ports

[ERnsTL]

From what I have gathered, litegraph.js currently does not support connecting multiple connections to or from a single port (array ports / index ports). A situation like that (generic example graphic):

Is this a known issue, or any plans regarding priority / roadmap?

If I oversaw this in the Demo, please forgive me.

How would one go about adding these features? Pointers on where to start appreciated.

Multiple outputs work fine... the problem with multiple inputs is the graph is parsed in reverse, from the final node back... and when it reaches a split it has to make a decision. I guess one way to handle it would be to instantiate a new "job" every time it encounters a branch (again, headed in reverse, so a branch would be a multiple-input) but that could very quickly become unreasonable, to attempt to instantiate each possible combination. Some of the graphs I've used could have thousands, easily.

Look at your example... imagine parsing it in reverse... do you see the ambiguity there?

Edit: Just wanted to note that I make use of Litegraph as it is implemented in ComfyUI (listed on the main page) and it definitely does allow for multiple output connections. I'm not sure if that is something they added themselves or not though, I've never used litegraph by itself/"pure"

Multi output works just fine.
Multi input should be allowed by the node itself. A multi input event type would work fine if correctly coded, a multi input "object" reference could execute multiple times for each element, a multi input that would accept a single value or an array could consider the single inputs as part of the array.
Anyway there are many places in the library to be recoded, that's a big challange.
A solution is using helpers nodes in the middle: for events using a sequencer event node, for other types a node that allows dynamic inputs and merge em into an array and that use that as input (alternatively one could directly code the dyn multi input in the final node itself)
