Overview of this book

jQuery UI is the quintessential framework for creating professional user interfaces. While jQuery core lays the foundation for interaction with the DOM and handling events, jQuery UI fills in the user interaction gap. This book will give you a huge productivity boost out of the box with jQuery UI, and help you understand the framework, inside and out."jQuery UI Cookbook" provides you with practical recipes featuring in-depth coverage of every widget in the framework, including how to address limitations that impact your everyday development activities with these widgets. You'll get a better idea of the big picture – how the framework is composed, how the widgets relate to one another, and how to build on those patterns.Be it a minor tweak on the visual design of a progress bar or a fundamental change in a widget to meet your needs, "jQuery UI Cookbook" covers scenarios both big and small. You can show reminders as tooltips, apply a variety of effects to the menu widget, and start interactions between the dialog widget and API data using deferred objects. These and many more interesting tasks are covered in this book, which can be done with smooth learning and great understanding. You will see how button widgets can fill the width of their containing element, making the layout more consistent. Tabs can be sorted and moved between widgets. You will learn how to do all these things within the context of the big picture, by finding out why the components work the way they do, making you well-versed in jQuery UI.

Highlighting the active menu item

With menu widgets, depending on how the items are configured, the only way to tell if an item is active is when the page URL changes as a result of an item being clicked on. The menu items don't give any obvious indication that anything has actually happened. For example, the item in a menu, once clicked, could change the visual state. This is especially helpful if the developer is using the menu widget as a navigational tool in the user interface. Let's look at how we can extend the capabilities of the menu widget in order to provide this functionality using parts from the theme framework.

Getting ready

We'll use the following HTML code for our menu example here. Notice that this particular menu has a nested submenu:

<ul id="menu">
    <li><a href="#first">First Item</a></li>
    <li><a href="#second">Second Item</a></li>
    <li><a href="#third">Third Item</a></li>
