One method I have found useful: 1) Store all navigation information in a database. 2) Create an array to contain all navigation items and store it in an application variable. 3) Create a structure within each array item containing all display information, such as user permissions, section display information, text or the url of the graphic. Example:
application.navitems[i] = structnew(); temp = structinsert(application.navitems[i], section_id, '1'); temp = structinsert(application.navitems[i], image, 'home.jpg'); temp = structinsert(application.navitems[i], user_level, '3'); temp = structinsert(application.navitems[i], alt_text, 'Return to the Home Page for this Section'); ...etc. 4) Create the navigation bar as a separate circuit in your application. Call it via CFMODULE within your display template. Otherwise just do an include. Consider caching the nav bar where appropriate to conserve server resources. This method is especially good if the navigation bar needs to be dynamic on a per-user level, i.e. if you have a lot of security in your application and want to include links only to the content the user has permission to see. What I often do is create a client variable containing all of the user's permissions (in this case, the section_id) and generate the navigation bar by comparing the contents of the application and client variables. One other thing I like to do is use autoimageeffects (a COM object) to produce dynamic images for the navigation bar. I have the administration section of my intranet set up to dynamically build the images for navigation bars in anti-aliased postscript text whenever I add a new section to site. Of course, I have found both of these techniques easier to do using CFCs... more on that later.
