Setting the SharePoint 2007 Navigation Flyout Level
One of the biggest improvements with SharePoint 2007 has been navigation. The breadcrumbs help and the tabs make a lot of sense. One of the nice features of the tabs is that you can have an automatic flyout menu for subsites. Let's say you have a top level 'Clients' tab with a subsite per client. The navigation will allow you to hover over the 'Clients' tab and see a flyout menu with links to each client site (automatically). Very nice!
Let's say you have Project sites per client. When you hover over your Clients tab, you don't get an automatic second level for project sites. Why? The default setting is set to only show one level for the flyout. How do you change it? Look for the 'MaximumDynamicDisplayLevels' property in the default.master file. It is set to '1'. Change it to '2' and you have two levels of flyout navigation from your top site. Done.
