Forms in the backend of type FK, MultiCombo have a 'typeahead' filter, you start typing and drop down starts to limit the results

ON the front end (replicable in sandbox) the same fields do not have the built in filter box. Both front and backend (of sandbox). You can start typing the word and the select moves down to that option, but the way the field is rendered in admin and site is totally different.

This is replicable on sandbox.

How can I get my FK Select boxes on the SITE to look and perform like they do in the admin area

Thanks

Works for me correctly in frontend?

I am loosing my marbles... its working fine for me now as well..

This is handled by "chosen" library.

It can be many possibilities, but the most probable is a javascript error BEFORE to load the chosen library.
It is maybe possible that even in sandbox, your component has fired an error.

In this case, the reflex is to open the developer console and have a look.
