++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. +
+ +
+A custom resultFormatter is used to format the Flickr results in the AutoComplete dropdown list, and a custom select event handler is used to override the default selection logic.
