I might have node that contains tens of thousands child nodes.

I'm trying to figure out how to lazily load node children (infinite scrolling).

I can load all children in one go (like it works currently) but it may take minutes to load such amount of a data (in current tests biggest nodes are ~14MB of json data). So is there way to load them like in grid dynamically?

Another option could be grouping by multiple columns in grid, but I haven't found any solution for that either.
