If you are using jQuery, one that I have already used and is quite easy to use is bootstrap tags input .

  

OBS: It only works until the Bootstrap version 3.3.7 

$("input").tagsinput('items')
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-tagsinput/0.8.0/bootstrap-tagsinput.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><scriptsrc="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-tagsinput/0.8.0/bootstrap-tagsinput.min.js"></script>

<input type="text" value="teste" data-role="tagsinput" />

You're using jQuery, you could use a plugin like TaggingJS and with this line you would solve your problem. $('#inputDaTag').tagging();

I used this and it was really cool:

Just reference the js and css files on the page and leave your input like this: 

 <input id="first_name" type="text" data-role="tagsinput" class="form-control">
