Autocomplete
Search and filter based on user input values, allowing users to quickly find and select from a list of preset values.
For more details about the autocomplete widget, please view the API documentation Autocomplete Widget.
Default function
When you type in the input field, the Autocomplete widget provides corresponding suggestions. In this example, suggestions for programming languages are provided, you can try it by typing "ja" and get Java or JavaScript.
The data source is a simple JavaScript array provided to the widget using the source option.

Contains accents
The autocomplete field uses a custom source option to match result items with accented characters, even if the text field does not contain accented characters. However, if you type accented characters in the text field, unaccented result items are not displayed.
Try typing "Jo" and you will see "John" and "Jörn", then type "Jö" and you will only see "Jörn".

Combobox
A custom widget created by Autocomplete and Button. You can type a few characters to get filtered results based on your input, or use the buttons to select from a full list.
The input is read from an existing select element and passed to Autocomplete with a custom source option.
This is an imperfect widget that is not supported. This is purely to demonstrate the autocomplete customization feature. For more details on how this widget works, check out the related jQuery article here.

The Autocomplete component gives suggested results as you type characters in the text field. In this example, when you type at least two characters into the text field, the name of the associated city is displayed.
In this example, the data source is geonames.org webservice. Although the city name is in the text field after selecting an element, more information is displayed to find the correct entry. Data can also be called back and displayed in the results box below.

Remote Data Source
The Autocomplete component gives suggested results as you type characters in a text field. In this example, when you type at least two characters into the text field, the name of the associated bird is displayed.
In this example, the data source is a server-side script that returns JSON data, specified with a simple source option. In addition, the minLength option is set to 2 to prevent the query from returning too many results, and the select event is used to display some feedback.

Remote Cache
When you type characters in the text field , the Autocomplete component gives suggested results. In this example, when you type at least two characters into the text field, the name of the associated bird is displayed.
In order to improve performance, some local caches are added here, and others are similar to remote data source instances. Here, the cache only holds a single query and can be extended to cache multiple values, one value per entry.
