This example uses the Flickr Search API (via YQL) to allow the user to select photo results based on a search query. After each photo is selected, it's added to the collection of photos displayed below the input field.
</p>
<p>
A custom <code>resultFormatter</code> is used to format the Flickr results in the AutoComplete dropdown list, and a custom <code>select</code> event handler is used to override the default selection logic.
