automate the sidebar using javascript to get menu content

**== CAN NOT use php for this. we are using lasso instead of php ===** --------------------------------------------------------------------------------------------------------- I want to automate the content of our sidebar. [login to view URL] I would like it to show, as active, the current page, and to also list the pages that are under that same tab in the menu. We have about 6 tabs in the menu, and there's about 200 pages in our website. here's a map [login to view URL] Ideally, the "Contact us" page would have on the sidebar everything that's in the about us section of the navigation menu bar. Almost none of the pages are nested inside folders, 90% are based out of the root folder. I wasn't going to nest each category inside a folder, but rather leave all of them flat. You can see that, if you navigate through the menu, there's no folders and they're all coming out of the root folder... so none of the pages' urls are any different than [login to view URL](page names goes here). So, I need a javascript or jquery code that I can include into the sidebar, and that will recognize what page its on to mark it as active, and will populate the sidebar with relevant content.
