Hidden flag for nodes

[harrycollin]

It would be great if we can exclude nodes from rendering based on a flag/property in the data (Example: hidden: true). My data structure contains children that shouldn't be rendered. Reconstructing the data would be difficult and would break references in other parts of my app. I feel like this should be something that's quite simple. Perhaps I've even missed something in the documentation which allows for this behaviour.

Interesting use case. I suppose this could be added in a future version.
