Typeahead is a AngularJS version of Twitter Bootstrap typeahead plugin

This directive can be used to quickly create elegant typeheads with any form text input.

It is very well integrated into the AngularJS as:

• it uses the same, flexible syntax as the select directive (http://docs.angularjs.org/api/ng.directive:select)
• works with promises and it means that you can retrieve matches using the $http service with minimal effort
