Select2

Select2 is a jQuery based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results. Look and feel of Select2 is based on the excellent Chosen library.

What Does Select2 Support That Chosen Does Not?

Working with large datasets: Chosen requires the entire dataset to be loaded as option tags in the DOM, which limits it to working with small-ish datasets. Select2 uses a function to find results on-the-fly, which allows it to partially load results.
Paging of results: Since Select2 works with large datasets and only loads a small amount of matching results at a time it has to support paging. Select2 will call the search function when the user scrolls to the bottom of currently loaded result set allowing for the 'infinite scrolling' of results.
Custom markup for results: Chosen only supports rendering text results because that is the only markup supported by option tags. Select2 provides an extension point which can be used to produce any kind of markup to represent results.
Ability to add results on the fly: Select2 provides the ability to add results from the search term entered by the user, which allows it to be used for tagging.
