jWizard can take your boring HTML forms and turn them into a Windows Wizard-like interface.

The require markup and setup is simple and straightforward.

With nothing more than this:

<div id="wizard">
	<div title="Step 1"></div>
	<div title="Step 2"></div>
	<div title="Step 3"></div>
	<div title="Final Step"></div>
</div>

and this:

$(document).ready(function() {
	$("#wizard").jWizard();
});

The rest of the HTML as well as the JS that you need for a slick wizard interface is automatically generated and handled behind the scenes.

By digging into the configuration, even more functionality is available. All of it is well-documented here and there is a complete set of demos here.
