[jQuery] Accordion-Like Menu: Setting (and removing) class on active item

[mike]

Hi

I tried to put together an easy accordion-like effect:

There is one problem: the selected-class will not be removed if all
items are closed (again). The class ".selected" should be removed if
no div is visible. How do I achieve this? "toggleClass" did not help
either.

Thank you very much for your help!
