Site Map

Abstract

Site Map is a very powerful part of Lift that does essentially what it says: provides a map (menu) for your site. Of course, if it only generated a set of links on your pages, we wouldn’t have a whole chapter dedicate to it. In addition to basic menu generation functionality, Site Map also provides

• Access control mechanisms that deal not only with whether a menu item is visible but whether the page it points to is accessible

• Grouping of menu items so that you can easily display portions of menus where you want them

• Nested menus so you can have hierarchies

• Request rewriting (similar to URL rewriting that we covered in Chapter 3)

• ▪|State-dependent computations for things like age titles, page-specific snippets, and so on The beauty of Site Map is that it’s very easy to start out with the basic functionality and expand it as needed as you grow.
