In Unreal, How do I hide function inputs based on Enum selected?

Question

I'm created a blueprinteditable function. First parameter is an Enum. The rest of the parameters should either be hidden or visible based on the Enum selected.

Like "EditConditionsHide" but for UFunctions.

For Reference, in Blender Geometry nodes, there are several nodes that alter available inputs based on an enum selection. Like "Quadrilateral" Node will have "width/height" when "Rectangle" is selected, but will have 4 vectors (Point 1-4) when "Points" is selected.

I'm trying to create new nodes for Unreal's Geometry Scripting that matches the function and layout of nodes in Blender's Geometry Nodes.

I haven't found any information on anything to try. All the documentation on Ufunctions that I've found doesn't give any option to hide parameters based on enum input.

This is not possible with vanilla UFUNCTIONS. You need to create your own custom K2Nodes. They are not trivial to make. I would suggest to split your function into multiple functions instead.

If you want to go down the route of custom K2Nodes, here is a good starting point for creating your own custom nodes: https://olssondev.github.io/2023-02-13-K2Nodes/
