Another good option is Selectize.js. It feels a bit more native to Bootstrap.

Does the basic HTML5 datalist work? It's clean and you don't have to play around with the messy third party code. W3SCHOOL tutorial

The MDN Documentation is very eloquent and features examples.

Can i suggest http://www.jqueryscript.net/form/Twitter-Like-Mentions-Auto-Suggesting-Plugin-with-jQuery-Bootstrap-Suggest.html, works more like the twitter post suggestion where it gives you a list of users or topics based on @ or # tags,
