If your hierarchy exists within a logical hierarchy, you
may want to place a series of breadcrumbs to give the user a sense of
context and give them a way to navigate up the tree to projects which
might contain the current project as a subproject. To configure
breadcrumbs, add a breadcrumbs element to the
body element in the site descriptor. Each
item element will render a link, and the items in the
breadcrumbs element will be rendered in order. The
breadcrumb items should be listed from highest level to lowest level. In
the following site descriptor, the Codehaus item would be seen to
contain the Mojo item.
Example 10.15. Configuring the Site's Breadcrumbs
<project name="Sample Project"> ... <body> ... <breadcrumbs> <item name="Codehaus" href="http://www.codehaus.org"/> <item name="Mojo" href="http://mojo.codehaus.org"/> </breadcrumbs> ... </body> </project>
