my $tree_view = Tree::Simple::View::DHTML->new($tree);

## more complex examples

# using the CSS properties
my $tree_view = Tree::Simple::View::DHTML->new($tree => (
list_type => "ordered",
list_css => "list-style: circle;",
list_item_css => "font-family: courier;",
expanded_item_css => "font-family: courier; font-weight: bold",
link_css => "text-decoration: none;"
));

# using the CSS classes

expanded_item_css_class => "myExpandedListItemClass",
link_css_class => "myListItemLinkClass"

my ($tree) = @_;
return "" . $tree->getNodeValue()->description() . "";

# add a radio button element to the tree
# with the name of 'tree_id'
radio_button => 'tree_id'
));

# print out the javascript nessecary for the DHTML
# functionality of this tree
print $tree_view->javascript();
