AutoSuggest

jQuery Autocomplete allows you to easily create autocomplete and autosuggest boxes for text input fields.   Built with focus on performance - results for every query are cached and pulled from local cache for the same repeating query. If there are no results for particular query it stops sending requests to the server for other queries with the same root.  

MagicSuggest is an auto-suggest combo with bootstrap theme using jQuery. It is a highly flexible auto suggest combo box in the line of Bootstrap themes and has many configuration options that one can customize.    

Address Picker is not just a jQuery autocomplete filled by google map geocoder suggestions. It automatically displays selected address on map, even while you navigate in autocomplete suggestions. And this address picker can get the locality, district, state/province, country, postal code, latitude and longitude of this selected address at the same time.
