this is hardly something brand new, this looks bettter and works just as well :

I'm sorry but progressive enhancement of a select tag into an autocomplete element isn't quite news worthy.

Exactly my thought. Chosen has the advantage of working moo tools, jquery or prototype. There's also a drupal plugin. It doesn't have alternate spellings support, but that should be really simple to add.

Does chosen have an equivalent to what this selector does with data-alternative-spellings?

[thegorgon]

no, but again, that wouldn't be that hard to add.
