Top Link Bar in SharePoint 2010 Team Sites
Each team site has its own Top Link bar — a common navigational element used to provide access to resources across the entire site. The Top Link bar is a series of tabs that sit in the header on a page in the SharePoint 2010 site.
The tabs that appear in the Top Link bar display the hyperlinked titles to a subsite or page in the site. Tabs may also expand to display content from within the site.
By default, the Top Link bar displays links to resources on the top-level site of the site collection. You can customize the bar so it shows only the resources for the current site and its subsites.
You manage the Top Link bar with the Top Link Bar page. To access the page, follow these steps:
Browse to the site where you wish to modify navigation and choose Site Actions→Site Settings.
The Site Settings page appears.
In the Look and Feel section, click the Top Link Bar link.
The Top Link Bar page appears. You must have at least Design permissions to access this page.
Click the New Navigation Link link and then enter the URL and name for the link you want to appear in the tab in the Type the Web Address and Type the Description text boxes.
The link appears in the Top Link bar.
To remove or modify an existing tab in the Top Link bar:
Navigate to the Top Link Bar page.
Click the Edit button next to the item you wish to modify.
Edit the entry or click the Delete button to remove the tab altogether.
