Exposing params or methods for CSS generation

I think it could be possible to accept a generateCss function in the params. If it is not supplied the original one would be used and adding a helper method to get the tree depth.

Or/And maybe I could add a function to return the generated CSS as a string, so the parent component could decide where to put it, or if multiple trees are on the page merge them.

What do you think?

Ooh, that sounds like a great idea.

I think overriding generateCss sounds better if you want to keep wooden tree working (indented) out of the box.

But OTOH I'd also be OK with just documenting what we need to do, so both work.

I meant override as well. I add this feature to my todo list.

I can do the css fix then, or you can create a separate PR for it if you have the time :)
