This is the demo for the frameless layout of the TreeView. For instructions on
this type of layout and others, check the online Instructions on
the Web page.
To simplify the demo, most links on the tree actually reload the same page (only
with different arguments for different pictures). In your site, you will probably
be linking to different pages, and many of them will also contain the tree. This
way the user can jump from page to page clicking the tree.
Note how some of the expandable/collapsible nodes have a hyperlink on their
name (the folder itself can load a page) and others don’t. The two types were mixed
here for demo purposes.
