We are trying to create a site map with the ‘Table of contents web part’. We would like to hide some sites. My question is how to set a hidden site? Use the Tree View and Navigation entries in the Site sttings? Or modify the site properties? One thing I can do is to create a new LevelStyle.xsl and point the web part file to the new xsl and re-write code to filter out the unwanted sites. But it takes a lot of time.
