Simplest example of Select2 doesnt working
Question
i'm trying to use Select2 select boxes, but it doesnt work on my page. My js skills is poor, so I try to do simplest example. I'm using bootstrap library. Whole code looking like:
<!DOCTYPE html> <html lang="pl"> <head> <meta charset="utf-8_polish_ci"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" integrity="sha384-9gVQ4dYFwwWSjIDZnLEWnxCjeSWFphJiwGPXr1jddIhOegiu1FwO5qRGvFXOdJZ4" crossorigin="anonymous"> <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.6-rc.0/css/select2.min.css" rel="stylesheet" /> <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.6-rc.0/js/select2.min.js"></script> <link href="../inc/bipro.css" rel="stylesheet" type="text/css"> <title>Test</title> </head> <body> <br> <div class="container"> <div class="row justify-content-center"> <div class="col-md-6"> <div class="card"> <div class="card-header"> select2 </div> <div class="card-body text-center"> <select class="aaaa form-control"> <option value="">wybierz</option> <option value="1">banany</option> <option value="2">cytryny</option> <option value="3">jabłka</option> </select> </div> </div> </div> </div> </div> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.0/umd/popper.min.js" integrity="sha384-cs/chFZiN24E4KMATLdqdvsezGxaGsi4hLGOzlXwp5UZB1LY//20VyM2taTB4QvJ" crossorigin="anonymous"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js" integrity="sha384-uefMccjFJAIv6A+rW+L4AHf99KvxDjWSu1z9VI8SKNVmz4sk7buKt/6v9KI65qnm" crossorigin="anonymous"></script> <script> $(document).ready(function() { $('.aaaa').select2(); }); </script> </body> </html>

You aren't including jQuery which is required for both Bootstrap and Select2.
<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>
Make sure jQuery is imported before Bootstrap and Select2
You're missing the name="" property on your select . I'd also rename that class to something that makes sense, like js-select
<select class="js-select form-control" name="fullnames">
<option value="0">wybierz</option>
<option value="1">banany</option>
<option value="2">cytryny</option>
<option value="3">jabłka</option>
</select>
Then your script will look like this:
<script type="text/javascript">
$(document).ready(function() {
$('.js-select').select2();
});
</script>
