Silo children menu

[binhwpo]

Hi @jcollings Since you are open to contribution, I'd like to give some more ideas.

In the past there were a silo categories plugin but I could not find it again. Is it of any chance you considered to do this in a next version?

Basically what I want is to show sub categories of the current active menu item as another sub menu.

I really hope this can be sort out. And I will sure contribute if it fits in.

Thanks.
