NAME

HTML::TreeStructured - Perl extension for generating tree structured HTML

SYNOPSIS

use HTML::TreeStructured;

### Describe tree via collection of Node and its properties

### Method 1: Via ArrayRef
###
### Node can be a string or '/' concatenated strings to show ancestry
### Properties are name/value pairs

my $tree1 = [
	['/aaa', 	color => 'green'],
	['/aaa/bbb'	mouseover => 'This is addl info'],
	['/aaa/ccc',	color => 'red', active => 0]
];

### Method 2: Via Hashref

my $tree2 = {
	aaa => {
		color => 'green',
		bbb   => {
			mouseover => 'This is addl info',
		},
		ccc   => {
			color	=> 'red',
			active	=> 0,
		},
};

Interpreted Node Properties:

color		= Color of the node name
mouseover	= Mouse Over text for the node (Info image is displayed next to node)
active		= 0 would cause strike thru on node
highlight	= color code used for marker highlight of node
url		= URL to hyperlink the node
closed		= 1 if node be closed on default display (default, all nodes are open)
comment		= Text to display next to node in bold


### Now get HTML equivalent for the tree
### The associated JavaScript for nodes close/open and ExpandAll/CollapseAll is generated alongside

$tree_html = HTML::TreeStructured->new(
	name         => 'tree_name',
	image_path   => '/images/',
	data         => $tree1,
	title        => "My Tree",
	title_width  => 300,
	level        => {},     ### If scalar, close BEYOND this depth. Depth start at 0.
				### If Hash, close for depths specified in keys
)->output;

### The same module can be used to generate FAQ - see "examples/faq.cgi"

I have been using HTML tables for structuring HTML presentation. After seeing HTML::PopupTreeSelect from Sam Tregar <sam@tregar.com> I liked the idea of stylesheets to indent HTML and adapted the same.
