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.

One approach to separating two categories of autocomplete data might be to have two distinct fields, each with their own autocomplete widgets. Another would be to introduce the notion of a category into the widget itself. When the drop-down menu appears to suggest items for the user, they will also see the category the item belongs to. To do this in the autocomplete widget, we need to change both how the widget understands the source data, and how the menu items are rendered.

How to do it...

We're going to extend the autocomplete widget in order to change how the menu items are rendered. We also need to consider the data passed into the widget as the source.

( function( $, undefined ) {

$.widget( "ab.autocomplete", $.ui.autocomplete, {

    _renderMenu: function( ul, items ) {

        var that = this,
            currentCategory = "";

        items.sort(function( a, b ) {
            return > 

        $.each( items, function( index,...
