Is it possible to have the accordion expand and open a new page on click


Hello,
I have an accordion menu working fine however I have been asked to do
something that does not seem possible but I thought I'd check. The
menu structure looks like this:
Category 1
Subcategory
Subcategory
Category 2
Subcategory
Subcategory
The Category 1 and 2 and the SubCategories are links to other pages.
If the event is set to 'mouseover' and they click on Category 1 a new
page opens. If the event is 'click', the accordion just expands. What
they want is both, click on Category 1 and have a new page open with
the Category 1 expanded to show the sub categories.
I'm out of my element here so if this is possible and an example is
handy, I'd appreciate it. Thanks.
