Scenario: All sites in a site collection share the same top link bar for consistent global navigation.
Site A (top-level)
Site A1 (2nd level)
Site A1a (3rd level)
Site A2 (2nd level)
etc.
Problem: When site A1 is active, tab "A1" is highlighted. When site A1a is active, no tabs are highlighted. And the bread crumbs do not include site "A1." So the user has no context to where they are in the site taxonomy.
In MOSS 2007 the behavior is different. Tab "A1" is highlighted when site A1 or any of its subsites is active. So when site A1a is active, tab "A1" is highlighted and the user knows where they are. This is good.
Question: How can I make SharePoint 2010 highlight the top link bar tabs in a similar manner to MOSS 2007?
