Filter Tree Structure

My customer wants a tree structure with three levels for filtering purposes. (Use Case: Types and respective subtypes of beer). How do I do this in Mendix (I hope this is an option)? I’ve already tried to use tree nodes connected to a certain entity, but it wasn’t possible to drop check box filters inside (which is requested by our customer). Does somebody have another idea?

We've tried something similar and used a "FilterController" NPE to hold the search text, and then set the data source of the treenodes to use XPath and refer to the FilterController text using contains()
