bootstrap drop down menu doesn't open

Question

I am having trouble getting my dropdown's to work. I can get the navbar to show up perfectly, but when I click on "Dropdown" (either of them) it does not display the dropdown menu. I have tried looking on other posts about this, but nothing that fixed everyone's problems helped. Here is the code

<head>
    <meta charset="UTF-8">
    <title>Landing Page</title>
    <meta http-equiv="X-UA-COMPATIBLE" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <script type="javascript" src="dist/js/bootstrap.js"></script>
    <script type="javascript">
        $(document).ready(function() {
            $(".dropdown-toggle").dropdown();
        });

    </script>
    <link href="dist/css/bootstrap.css" rel="stylesheet">

<body>
<div class="navbar-wrapper"><!-- navbar start -->

                <div class="navbar-header">
                   <button type="button" class="navbar-toggle collapsed" data-toggle="collapse"
                           data-target="#navbar" aria-expanded="false" aria-controls="navbar">
                       <span class="sr-only">Toggle navigation</span>
                       <span class="icon-bar"></span>
                       <span class="icon-bar"></span>
                       <span class="icon-bar"></span>

                        <li class="dropdown">
                            <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="true">Dropdown <span class="caret"></span></a>
                            <ul class="dropdown-menu">

                            </ul>
                        </li>

                </div>
            </div>
        </nav>
    </div>
</div><!-- navbar end -->
<!-- Placed at the end of the document so the pages load faster -->

In my case, I loaded bootstrap JS twice. Removed duplicate one and it worked.

I had the same problem, I thought it was a CSS problem, but your answer made me understand that it was a JS problem, thanks a lot!

The problem is in your stylesheet or bootstrap js Link (look at below). Check again!

<script type="javascript" src="dist/js/bootstrap.js"></script>
<link href="dist/css/bootstrap.css" rel="stylesheet">

I tried openning you code with jsFiddle and it worked perfectly. maybe there is a problem with one of your bootstrap files..? Try downloading another bootstrap js file

Here is the working example - https://jsfiddle.net/ckcrogo6/ (The HTML code is exactly the same as the code you posted)

Used the bootstrap files found here - https://www.bootstrapcdn.com/

<body>
<div class="navbar-wrapper"><!-- navbar start -->
<div class="container">
    <nav class="navbar navbar-inverse navbar-static-top">
        <div class="container">
            <div class="navbar-header">
               <button type="button" class="navbar-toggle collapsed" data-toggle="collapse"
                       data-target="#navbar" aria-expanded="false" aria-controls="navbar">
                   <span class="sr-only">Toggle navigation</span>
                   <span class="icon-bar"></span>
                   <span class="icon-bar"></span>
                   <span class="icon-bar"></span>
               </button>
                <a class="navbar-brand" href="#">Project name</a>
            </div>
            <div id="navbar" class="navbar-collapse collapse">
                <ul class="nav navbar-nav">
                    <li class="active"><a href="#">Home</a> </li>
                    <li><a href="#about">About</a> </li>
                    <li><a href="#about">Contact</a> </li>
                    <li class="dropdown">
                        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="true">Dropdown <span class="caret"></span></a>
                        <ul class="dropdown-menu">
                            <li><a href="#">Action</a></li>
                            <li><a href="#">Another action</a></li>
                            <li><a href="#">Something else here</a></li>
                            <li role="separator" class="divider"></li>
                            <li class="dropdown-header">Nav header</li>
                            <li><a href="#">Separated link</a></li>
                            <li><a href="#">One more separated link</a></li>
                        </ul>
                    </li>
                </ul>
            </div>
        </div>
    </nav>
</div>

Hope this will help
