bootstrap navbar hamburger menu does not work in django app - html

Question

I have developed a django app but for some reason the bootstrap navbar won't show menu items on mobile phone
Whenever I run my app on a mobile device's web browser the hamburger menu does not extend to show my nav items...it is very odd.
<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
<a class="navbar-brand" href="#"><img src="{% static 'images/logo.png' %}"></a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
{% if user.is_authenticated %}
<ul class="navbar-nav mr-auto">
<li class="nav-item">
<a class="nav-link" href="{% url 'dashboard:transactions' %}">Transactions</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'dashboard:quote' %}">Quote Tool</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'dashboard:tracking' %}">My Projects</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'dashboard:home' %}">Home</a>
</li>
<a class="nav-link" href="{% url 'dashboard:support' %}">Support</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'logout' %}">Logout</a>
</li>
</li>
</ul>
{% else %}
<ul class="navbar-nav mr-auto">
<li class="nav-item">
<a class="nav-link" href="{% url 'register' %}">Sign up</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'login' %}">Login</a>
</li>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'dashboard:home' %}">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'dashboard:quote' %}">Quote Tool</a>
</li>
</ul>
</div>
{% endif %}
</div>
</nav>

Answer 1

Your code works fine in my Django/Bootstrap-project. You should double check that you have imported the Bootstrap JS correctly, as this is probably the reason why the hamburger won't expand. Try using the starter template https://getbootstrap.com/docs/4.3/getting-started/introduction/ and see if it does the trick :)

Answer 2

As suggested by Patrick, I reloaded afresh js from the boot strap starter template hamburger menu started working on mobile.
