使用Symfony2自动完成

I've an input text field and with a simple AJAX, my user insert 2 or 3 letters and get the occurence from my entity. How to add an entity in a input text field as an autocomplete with Symfony2 ? Thanks for your help.

You can try GenemuFormBundle which has an interface to jQuery UI autocomplete. You can have a look at documentation here: https://github.com/genemu/GenemuFormBundle/blob/master/Resources/doc/jquery/autocomplete/index.md
