Re: Sorting things on two levels

The output from the above should be as follows (I'm wrapping it in HTML list tags but have omitted them here for clarity -- I assume if I can get the sort working I can wrap the output without much effort):

Aardvarks, {ID}.
Bears.
    breeding, {ID}.
    feeding, {ID}.
    hunting, {ID}, {ID}.

Is there an easy way to do this?
