Ahhh... passing a handle as an argument. It seems so obvious now.
Thanks
I have actually already moved things to a helper, which makes more
sense anyway. The helper I have will suit my needs fine this time
around. It will be easy to wrap tags around the menu elements when I
get around to the CSS. Next time I will use the TreeHelper... I'm sure
it will save time.
Thanks again.
