Hi there,

Currently, we dont have those setting to check for empty sub-categories currently We only have this options http://take.ms/LKoED, that is to totally hide sub-categories from all categories views only.

But it would be best if you can submit a feature request regarding this issues by creating a new ticket on the forums and set it to "Feature Request", so everyone else could vote for it, the more people request on this, and we will priority consider it.

Please advice.
