site map, discussed in more detail later in this chapter, is a visual organization of files and links within your defined site. Shown in Figure 4.17, the Site Map Layout category facilitates configuration of the site map feature. Figure 4.17. Configure Dreamweaver's site map feature from the Site Map Layout category. [View full size image]   The Site Map Layout category can be broken down into the following list of features: Home page: Creating a site map begins with defining a home page. Generally, all pages in a website stem from a home page. For this reason, you'll want to browse to your home page file from here. In our case, the index.htm file should already be selected. Number of columns: Enter a number in this text box to set the number of pages to display per row in the site map window. Column width: Enter a number in this text box to set the width of the site map columns in pixels. Icon labels: Use one of these options to choose whether the name displayed with the document icons in the site map is represented as a filename or as a page title. Display files marked as hidden: Select this option to display HTML files you've marked as hidden in the site map. Hidden files will show italicized. Display dependent files: Choose this option to display dependent files in the site map. Dependent files are images or other non-HTML content that the browser loads when it loads the main page. Generally, the default options in this category will suffice. As long as the path to index.htm is listed in the Home Page text box, we're ready to move on. The File View Columns Category Like your operating system's file explorer, the Dreamweaver Site Management window (covered later) supports the customization of columns to be made visible or hidden. The File View Columns category shown in Figure 4.18 allows you to show or hide Name, Notes, Size, Type, Modified, and Checked Out By columns. Figure 4.18. Use the File View Columns category to show or hide columns in the Site Management window. [View full size image]   The File View Columns category can be broken down into the following list of features: Enable column sharing: Check this box to share file view column and custom file view columns with other members of a collaborative team. Add (+)/Remove () : Allows you to add a custom view column. After you've added the custom column, you can associate the column with a property of the Design Notes menu. Click the Remove () icon to remove a custom column. Dreamweaver does not allow you to remove built-in columns; they can only be hidden. Move Up/Move Down: Click the Move Up or Move Down icons in the top-right corner of the screen to reposition the file view columns. Repositioning the columns changes the arrangement of the columns in the Site Management window (moving from left to right). File View Columns list: Lists built-in and customized file view columns. Select a file view column from this list to interact with other configurable options on the screen. Column name: Allows you to name a custom file view column. Built-in file view columns cannot be renamed.
