Sub Menus

I'm taking a Drupal Gardens web site to my own hosting, and need to display in the sidebar the 'sub' menu items for the section the user clicked into. The Main Menu is across the top, with flyouts. Now, the sidebar needs to have menu items, not the top most level, just the fly outs.

There are many ways in D6 to do this. I'm now working in D7 and feeling out of sorts, given I want to give admin control over this. I've done it several ways in d6, including add on modules or my own custom php snippets.

I want to make a sub menu like timeonline in Drupal for a Newspaper website. I appreciate any help, insights, modules to be used to achieve this type of a menu.

Thanks a lot.
