I've looked through the documentation, and the FAQs, and Google... I'd like to uses tabs.xml and site.xml to create a menu sidebar that's persistent -- that is, even if I go to a subdirectory, the menu does not lose higher-level items. The goal is to maintain the same overall view of the site on all pages.

<http://www.PebbleAndAvalanche.com> the site I'm currently working on. The tabs work as expected, and so does the menu; if I select an item I get the correct highlights in the tab and the menu. However, the menu changes depending on where I am in the directory hierarchy, and I'd like to know if it's possible to avoid changning menus.
