With SharePoint 2010, we've noticed that the left-side navigation from the master page limits us to two levels -- "Add Heading" and "Add Link." We'd like to have a menu on the left that has at least one more level, like "Add Sub-Link". Are there ways to do this while not changing the master page?
Also, if we have a link that's related to that section of the site but not on the menu, if we navigate to it, the left navigation highlights the root item. Is there a way to fix this? Thanks.
