jQuery UI extras
jQuery UI extras includes datepicker and tooltips. Extras is disabled by default because it overrides plugins with the same name. To enable jQuery UI extras just uncomment <script src="assets/javascripts/jquery-ui-extras.min.js"></script> line at the end of the html file.

TOOLTIPS

Tooltips can be attached to any element. When you hover the element with your mouse, the title attribute is displayed in a little box next to the element, just like a native tooltip.

But as it's not a native tooltip, it can be styled. Any themes built with ThemeRoller will also style tooltips accordingly.

Tooltips are also useful for form elements, to show some additional information in the context of each field.

Hover the field to see the tooltip.
