Bootstrap navbar not collapsing back - html

I've been using bootstrap 4.3.1 for a laravel project and everything is working good but the bottom navigation bar that I'm using, expanded once, does not want to collapse back while in mobile view.
As soon as I click the collapse button, code changes into being collapsed and then instantly goes back to being expended.
What could be the issue here?
Here's the code for the navigation bar:
<nav class="navbar fixed-bottom navbar-expand-lg navbar-light">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavAltMarkup">
<div class="navbar-nav m-auto">
<a class="nav-item nav-link active" href="/">Home <span class="sr-only">(current)</span></a>
<a class="nav-item nav-link" href="/posts">Blog</a>
<a class="nav-item nav-link" href="/services">Service</a>
<a class="nav-item nav-link" href="/about">About</a>
</div>
<ul class="nav navbar-nav navbar-right">
<!-- Authentication Links -->
#guest
<li class="nav-item">
<a class="nav-link" href="{{ route('login') }}">{{ __('Login') }}</a>
</li>
#if (Route::has('register'))
<li class="nav-item">
<a class="nav-link" href="{{ route('register') }}">{{ __('Register') }}</a>
</li>
#endif
#else
<li>Create Post</li>
<li>{{ Auth::user()->name }} <span class="caret"></span></li>
<li>
<a href="{{ route('logout') }}"
onclick="event.preventDefault();
document.getElementById('logout-form').submit();" class="nav-item nav-link">
{{ __('Logout') }}
</a>
<form id="logout-form" action="{{ route('logout') }}" method="POST" style="display: none;">
#csrf
</form>
</li>
#endguest
</ul>
</div>
</nav>
Here's the HTML output of the above code from the browser:
<nav class="navbar fixed-bottom navbar-expand-lg navbar-light">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">

Some times it happens when you include bootstrap twice. Check your js files where bootstrap.js is referenced. Or include it globaly in webpack.mix.js documentation

I feel like i am missing something but i can't figure it out.
Instead of data-bs-toggle and data-bs-target use data-toggle and data-target.I solved your problem with the toggler, the rest is up to you... Work on your code! It leaves a lot to be desired ... ;-) Good Luck !

It doesn't look as though you have any dropdown-menu's inside the main navbar-nav list. Copy this for as many dropdown's as you need.
<ul class="navbar-nav">
<!-- Dropdown Start -->
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="servicesDropdown" role="button"
data-toggle="dropdown" aria-expanded="false">
MAIN DROPDOWN BUTTON
</a>
<ul class="dropdown-menu" aria-labelledby="servicesDropdown">
<li><a class="dropdown-item" href="#">DROPDOWN ITEM 1</a></li>
<li><a class="dropdown-item" href="#">DROPDOWN ITEM 2</a></li>
<li><a class="dropdown-item" href="#">DROPDOWN ITEM 3</a></li>
<li><a class="dropdown-item" href="#">DROPDOWN ITEM 4</a></li>
</ul>
</li>
<!-- Dropdown End -->

Bootstrap Navbar toggle icon button not showing nav items on click?

I have been using bootstrap in projects very smoothly, but then in one angular project, its navbar toggler icon button is appearing but not showing the nav items on clicking the button.
<div>
<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
<div class="container">
<a class="navbar-brand" href="#">Admin Header</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive"
aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="./home">Home
<span class="sr-only">(current)</span>
</a>
</li>
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="./about">About</a>
</li>
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="./services">Services</a>
</li>
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="./contact">Contact</a>
</li>
<li class=" btn-primary nav-item text-white" role="button">
<a class="nav-link text-white" (click)="logOut()" >logout</a>
</li>
</ul>
</div>
</div>
</nav>
</div>
This is the Navbar result:
On decreasing the width of the browser we have results something like this:
below is the code of index.html:
But on clicking on this button I am not able to see any nav items.
Works perfectly fine, you must be missing some script files.

Why is my bootstrap toggler not toggling?

I have followed the instructions and included the javascript packages into my file. However, whenever I click the toggle button, it does not toggle at all, why is that so? Does it have something to do with the version of my packages?
I have included some Django templating syntax, do ignore those

you are using bootstrap 5 syntax data-bs-toggle
but you using bootstrap 4 change data-bs-toggle to data-toggle
Check out the bootstrap 4 documentation

Django bootstrap dropdown button in navbar not working

I've tried other questions with similar topic with many different links to bootstrap but it was not working for me, none of them. Any clues why my dropdown button does not roll down when clicked (also does not when hovered either as this was the case for some people).

Bootstrap navbar toggle button not showing contents [duplicate]

This question already has an answer here:
menu toogle button not working in bootstrap 4
(1 answer)
Closed 4 years ago.
Currently when the screen is minimized, the toggle button appears, but I would like to be able to click it and see the contents of the navbar when the screen is regular size. Currently clicking it doesn't do anything. Is there a way to resolve this without JS?
This is my HTML page:

You don't need to write your own code to make it works, but you need to also include bootstraps js library and its dependencies (jQuery + popper.js), here you will find information how should you do it https://getbootstrap.com/docs/4.1/getting-started/download/
in case you have some issues with that let me know I will show you how to implement it to your code
#edit:
FYI bootstrap.css, provide for you only bunch of css classes which you can use for quick styling but it doesn't provides any interactivity unless those supported by css such as element hover or focus
