Another page menue bar with expanding and collapsing buttons

Hi Flynn,

I would like to have on the left side of my website a menu, which is only displaying the main pages. When I click on one of these buttons, I should get directed to that very page. In addition, the subpages should get displayed under thais main page in the menue bar. (expanding buttons)

When I click on another main page, the presently showed subpages should collapse and the subpages from now chosen main page should show up.

The same like in the header man page navigation. I think it is called suckerfish.

Right now the whole menue is static and shows all pages and if you also choose subpages, they are also static all displayed. My problem is, that the whole navigation is getting too long with static navigation.

Is it possible to include a plugin and use a totally different navigation style and type ?
