Hi Alex,

If you need sophisticated autocompletion, have a look at 

There is no Catalyst plugin but it's quite simple to integrate it into a Catalyst app :

a) write a Controller that will receive the Ajax requests and answer with a JSON datastructure (arrayref of possible values, or, if you want more complex behaviour on the client-side, arrayref of hashrefs with several fields for each returned entry).
b) serve the GvaScript.js file through Static::Simple or directly through your HTTP server
c) in your HTML page, include the GvaScript.js and write the JS code for initialising the Autocompleter object, giving it the URL for the Ajax controller and setting the appropriate options, as described in the doc. You can specify delays, case sensitivity, strictness, typeahead features, dependent fields, and many other options. 

If you need an example, install the Pod::POM::Web local documentation server and see how it works; it uses the autocompleter for perl functions and perl variables.

Good luck, Laurent Dami
