How to build a menu tree that is expandable with jQuery

Your html will need to link to the jQuery plugin in the head element

Your html markup needs to use a list like…

Tree Menu - toggle OR slideToggle animation


			Top Parent - Tier 1

Child - Tier 2

Pixelhandler - Tier 3
jQuery - Tier 3




Lower Parent - Tier 1


					Child - Tier 2

Grandchild - Tier 3 - One
Grandchild - Tier 3 - Two








Definition list - Term 1
Description not targeted, uses CSS classes to collapse/expanded view
Term 2
Description 2 with links listed

Pixelhandler
jQuery




Term 3
Description 4
Term 4
Description 4 with unordered list

menuTree plugin plugin uses a few CSS classes for visual design…

#myTree .menuTree:before {
	content: "[+] ";
}

#myTree .expanded:before {
	content: "[-] ";
}

#myTree .collapsed {
	display: none;
}

At the end of your html markup, before the closing body element use a script to setup the function…

$(document).ready(function() {

	$('#myTree').menuTree({
    	animation: true,
		handler: 'slideToggle',
		anchor: 'a[href="#"]',
		trace: true
	});

});

This plugin has default options which you may override. The animation option may use jQuery toggle or slideToggle methods, or just use the default css option to show/hide the child list(s).

When called with the animation: true option the plugin uses the handler option to select slideToggle or toggle method to add effects to the display of child menu(s). You may set the speed as you please, e.g. speed: ‘slow’. Also, you may indicate what the child menu(s) are marked up with, e.g. listElement: ‘ol’ instead of the default listElement: ‘ul’

The default options:

$.fn.menuTree.defaults = {

	// setup animation
	animation: false,
	handler: 'css',
	speed: 'fast',
	// setup hooks in markup
	listElement: 'ul',
	anchor: 'a[href="#"]',
	// uses 'tracer' plugin
	trace: false
};
