I had this problem. It didn’t work the dropdown or the Collapse menu when reducing the page to mobile version. I solved so...

  1. install the jquery npm install jquery --save

  2. in the archive angular.json check if in scripts is the path to jquery and bootstrap. Search for two paths to scripts and add in both.

    "scripts": [ "node_modules/jquery/dist/jquery.js", "node_modules/bootstrap/dist/js/bootstrap.js" ]

  3. Down below, you’ll find another scripts and also add. "scripts": [ "node_modules/jquery/dist/jquery.js", "node_modules/bootstrap/dist/js/bootstrap.js" ]

  4. Go to the app.module.ts and import the jquery

    import * as $ from 'jquery';

  5. Restart the server on the command line and make sure it’s solved.

In the documentation of Bootstrap shows that the <nav class="navbar navbar-default" role="navigation"> should come before your <div class="container"> .

Making this change the Collapse navbar will work.

I tried to recreate an online jsFiddle code above your question, but I don’t quite understand what your goal is or what you’re trying to create, but to create a dropdown list with Bootstrap, just use:

<div class="dropdown">
    <button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Java
        <span class="caret"></span>
    </button>

    <ul class="dropdown-menu">
        <li><a href="#">jmeter</a></li>
        <li><a href="#">EJB</a></li>
        <li><a href="#">Jasper Report</a></li>
        <li class="divider"></li>
        <li><a href="#">Separated link</a></li>
        <li class="divider"></li>
        <li><a href="#">One more separated link</a></li>
    </ul>
</div>

Well the code is right... You should not be importing bootstrap and jquery. You even downloaded those files and put them in the work folder?

I did this with your code and it worked.
