Sharepoint 2007: Multi tiered top navigation

I have a site within a site and would lik开发者_如何学运维e to see this site appear as a drop down menu in the top menu bar (ID="TopNavigationMenu"). In the default.master page I have edited the following: StaticDisplayLevels="2"

MaximumDynamicDisplayLevels="3"

In the Menu Navigation I added the top site to the global navigation area, but it doesn't display the sub sites on the top menu drop down.

Make sure that the option 'show subsites' in the navigation settings is checked for both your site as your subsite.
