how to get a 2nd submenu

Hi,

I’m running wordpress 2.7

I’ve searched and searched, and found nothing even referencing to my querey.

I’d love to have a secondary menu that is customised depending on what menu item on your primary menu was selected. For Example: you have 6 titles on your primary menu horizontally along the top, and when you click on one of these menu’s, a page appears with what ever you want to put on it, yet a second submenu appears vertically on one of the sides with several links to several other pages which you can click on. If you click on another menu item on your horizontal primary menu. Another page will appear with different items on your 2nd vertical sub menu.

Is this at all possible with wordpress? If so, is there a plugin that can do this?

Thanks,
Clint
