In the official documentation on Node Parts
it mentions about white colored socket inputs of the Collection Input Node
(its official documentation also doesn't mention much, only says "Collection to get the properties from").
Collection (white)
Used to pass a collection data-block.
But I can't find any collection data-block based Nodes which can connect to this. How to pass a specific collection to an Info Collection node in Blender 3.0.1?
@Chris: Thanks for bringing this to my attention. But I need it to be inside the node editor so I can do some conditional stuff as well.
