Whenever you need an input field, that will hold multiple tags-like words, by writing and pressing just Enter button, then you will definitely need this code snippet.

Here it is : 

<div class="form-group">
<label for="tags" style="display: block;">Tags</label>

<link rel="stylesheet" href="">
.label-info {
background-color: #CDCDCD;
border: 1px solid #ccc;
box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075);
display: inline-block;
/* padding: 2px 6px; */
color: #555;
vertical-align: middle;
border-radius: 4px;
max-width: 100%;
/* line-height: 22px; */
cursor: text;

.bootstrap-tagsinput {
width: 100%;
padding: 10px;

.bootstrap-tagsinput .tag{
color: #555;
font-family: "Poppins", Arial, sans-serif;
line-height: 1.4;
box-sizing: border-box;
text-decoration: none;
transition: .3s all ease;
text-transform: uppercase;
padding: 3px 10px;
margin-bottom: 2px;
margin-right: 4px;

font-size: 11px;
font-weight: 400;
<script src=""></script>
<script src=""></script>

<input type="text" class="form-control" id="tags" name="tags" data-role="tagsinput" placeholder="Write and click Enter" style="color:#555555;word-wrap: normal;">

In case you wanted to add tags based on an ajax request filteration process here is a sample code that makes use of ajax request to a laravel controller method that returns a json object that is represented as li in the suggestions div. clicking on it will add this new li value/text to the result

{{-- <script src=""></script>
<script src="{{asset('tags-input/bootstrap-tagsinput.min.js')}}"></script> --}}

<input type="text" class="form-control" id="tags" name="tags" value="{{ $snippet->tags }}" data-role="tagsinput" placeholder="Write and click Enter" style="color:#555555;word-wrap: normal;">


var theLastWrittenValue = '';
$("div.bootstrap-tagsinput > input").on('keyup', function(e){

if(e.keyCode == 13) {

let writtenValue = $(this).val();
theLastWrittenValue = $(this).val();

type: "get",
url: "{{url('/getTagSuggestions')}}/"+writtenValue,
/* data:formData, */
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
dataType: "json",
success: function (msg) {//alert('Success');

if(msg.length) {
$.each(msg, function(index, element) {

} else {

}).done(function (data) {//alert('donee');

}).fail(function () {
//alert('Failed to load.');

$(".suggestions").on("click", "li", function(){
let selectedValue = $(this).text();

//Remove Old tag
$('input#tags').tagsinput('remove', theLastWrittenValue);

//Add the new Tag
$('input#tags').tagsinput('add', selectedValue);

//now Empty the suggestions div

<div class="form-control suggestions" id="suggestions" style="height: auto !important;display: none;">
{{-- <li>Click</li>
<li>Thanks</li> --}}

Here is the laravel controller method used in the last example:

public function getTagSuggestions($tag='') {
$suggestions = [];
if($tag != '') {
$suggestions = Tag::where('tag', 'like', "%$tag%")->get('tag')->toArray();
return response()->json($suggestions);
