I've been trying to get my vertical navigation to load with the subsection of the current page expanded. I'm sure that this should be trivial, but I've been trying various approaches for nearly two hours now and am getting nowhere.

Things I have tried:

Using  pathClass, including the approach for wordpress described here

Using a brute force approach by calling showSuperfishUl();

Nothing seems to work! There seems to be quite a bit written about this for the horizontal superfish menus,

but very little for vertical menus. You can see an example page here.

Any and all help would be much appreciated!
