Chapter 15. Planning and Mapping Web Sit... > Changing Site Mapping Settings - Pg. 368

Planning and Mapping Web Sites 368 Your levels might be present but collapsed. Shapes that include links to additional levels in the site are dis- played with a plus (+) sign. You can expand the shape to see its links by right-clicking the shape, and then choosing Expand < Address >. For a large site, it's easiest to create a subpage first, and then expand the shape. For details, see "Formatting a Site Map Across Multiple Pages," page 412. Changing Site Mapping Settings You can exert a great deal of control over Visio's site mapping capabilities. Maybe you just need a list of graphics, or you need to find links to out-of-date pages. When you click Settings in the Gen- erate Site Map dialog box, you can do the following: · Change the number of levels in your site that Visio analyzes, the number of links per level, and the layout used for the site map on the Layout tab. · Choose the content to include and the shapes used in the site map on the Extensions, Protocols, and Attributes tabs. · Specify the scope of the site search and provide proxy authentication on the Advanced tab. To best use the options in the Web Site Map Settings dialog box you need a working knowledge of HTML and Web site structure. Knowing which attributes to tell a crawler to examine and which to ignore requires a certain amount of experience with HTML source code. For example, if you're trying to determine how many graphics are used on a site, you can disable Audio on the Extensions tab so that Visio doesn't include .wav files in your site map. Although you can also filter the view of your site map after it's generated and temporarily hide particular types of content from view, the Web Site Map Settings dialog box gives you more control over items you don't need to see in the first place. In addition, by disabling options, Visio can generate a site map more quickly, and you're less likely to end up with an unmanageably huge diagram.
