I was recently on a similar mission and I eventually settled with jQuery UI's autocomplete ^[1]. I am currently using jQuery UI 1.6rc2 and the autocomplete plugin is very well implemented and customizable. Here's an example:

<script type="text/javascript" src="jquery-1.2.6.js"></script>
<script type="text/javascript" src="ui.core.js"></script>
<script type="text/javascript" src="ui.autocomplete.js"></script>

<script type="text/javascript">
$('#search').autocomplete({
  url: 'suggestions.php', //jQuery UI 1.6rc2
  // source : 'suggestion.php', //jQuery UI 1.8.18
  width: 300,
  max: 10,
  delay: 100,
  cacheLength: 1,
  scroll: false,
  highlight: false
});
</script>

Autocomplete has been removed from the latest JQuery UI (since 1.6rc3). And the one you found in 1.6rc2, won't work with later version.

However, this guys has modified the code and make it work with later version.

As of jQuery UI 1.8.1, autocomplete is standard with the library.

This is quite easy-simple to integrate .This has got a lot of options with it

There's a rewrite of my autocomplete up on http://code.google.com/p/jquery-autocomplete/ (in an attempt to properly open source it). Please report any issues you find on the Google Code project.

That said, I fully endorse Jörn's excellent work on a jQuery UI autocomplete and his version will probably be more powerful/customizable eventually.

Dylan Verheul

i like the smart coding of James Smith,

Features ::

• one single .js file instead of lots ( jQuery Ui official plugin need four .js )
• HIGHLY customizable
• FRESH development

I tried a number of them, ended up with YUI's autocomplete ^[1] (yes, for use with jQuery), it's worked well for me so far. You can use YUI's Loader ^[2] facility to make it a fairly painless download and keep page loading times good.

As of today, only Dylan Verheul's version ^[1] worked for me without issues.
I tried the others but I was going crazy juggling between xml and json data output formats from PHP.
Dylan's gives a simple plain text option (JSON and XML are not difficult, just that if plain text works, you might find it easy and useful).
The server side code for the example is tiny ^[2] if you ignore the data array.
I used the autocomplete.css from Jörn Zaefferer's version ^[3] with the source on Dylan's page ... works fine.

You can find a simple autocomplete plugin on

http://blog.idealmind.com.br/projetos/simple-autocomplete-jquery-plugin/

It's a plug and play plugin with callback functions, and you can use multiple autocomplete on the same page.

This combobox has many useful option documentation ^[1] download ^[2].
