"is a general-purpose expandable/collapsable tree in the style of Microsoft Windows Explorer, Apple Macintosh Finder, or the navigations of many popular websites. It is highly customizable, feature rich, and degrades gracefully in older browsers or when javascript/css is unavailable." I'm not crazy about the fact that this uses tables, but I like it enough that :
use DHTML::ypXmlTree;
my $tree = DHTML::ypXmlTree->new();
my $folder = $tree->folder(name=>"weblogs");
$folder->file(name=>"aaronland",href=>"http://aaronland.net");
print $tree->as_html(),
I will try and release the code tonight, or in the morning.
