What is a Table of Contents Web Part?
A Table of Contents Web Part is a configurable component that you can add to a Web Part Page (Web Part Page: A special type of Web page that contains one or more Web Parts. A Web Part Page consolidates data, such as lists and charts, and Web content, such as text and images, into a dynamic information portal built around a common task.). You use the Table of Contents Web Part to automatically generate a site map that point to various parts of your Office SharePoint Server 2007 site collection. When you add a Table of Contents Web Part to a page, you specify which part of your site collection the Web Part should generate links to, how the links are presented, and how the links are organized.
