I would suggest that you have a configuration in which you specify which level gets filtered. if set to 1 the first parents are filtered, if set to 2, the first children are filtered, ignoring the parents. I suppose it could go further down than that, but that scenario seems to make the most sense. may be simply filterMode: parentFilter or childrenFilter
