Displays as an ordinary selectbox with an additional text-input for filtering the options. An adaption of the example at [1] for use with Django.

The code assumes the java script from [2] is downloaded into your media folder. Remember to output your form's media, for instance like: "{{form.media|safe}}", somewhere above your form.
