title: How to extend an existing jQuery UI widget?
body: <p>I am using jQuery v1.8.3 and jQuery UI v1.9.2. I would like to <em>extend an existing jQuery UI widget</em> (in my case the <a href="http://jqueryui.com/autocomplete">Autocomplete</a> widget) by adding and overriding just some options and methods but keeping the others functionalities as those present in the official release. How can I make that the "proper" (maybe, the "standard") way?</p>

  <p><em>P.S.</em>: I searched on the Web (<a href="https://github.com/scottgonzalez/widget-factory-docs">1</a>, <a href="http://wiki.jqueryui.com/w/page/12138135/Widget%20factory">2</a>, ...) and I found documentation mostly related to <em>creating a new</em> jQuery UI widget but not to extending an existing one.</p>
