I copied the official Bootstrap 4 example for dropdown menus but it is not working, that is nothing is dropped down.
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Dropdown</a>
<div class="dropdown-menu" aria-labelledby="dropdown01">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
Edit: In case anyone else is having this problem, I believe the solution for OP was that he had not imported popper.js.
Check that jQuery and all the relevant Bootstrap components are there. Also check the console and make sure there are no errors.

Add this code to your jquery
$('.dropdown').click(function(){
$('.dropdown-menu').toggleClass('show');
});
Assuming Bootstrap and Popper libraries were installed using Nuget package manager, for a web application using Visual Studio, in the Master page file (Site.Master), right below where body tag begins, include the reference to popper.min.js by typing:
<script src="Scripts/umd/popper.min.js"></script>
Here is an image to better display the location:
Notice the reference of the popper library to be added should be the one inside umd folder and not the one outside on Scripts folder.
This should fix the problem.
include them with this order
this will work
i dont know why :D
<!-- jQuery -->
<script src="js/jquery-3.4.1.min.js"></script>
<!-- Popper -->
<script src="js/popper.min.js"></script>
<!-- Bootstrap js -->
<script src="js/bootstrap.min.js"></script>
It's an issue with popper.js file. What I found at the official site was that bundle files include popper in itself but not jquery. I managed to fix it by adding link to these files:
bootstrap.bundle.js
bootstrap.bundle.min.js
I removed popper.js however since it comes within the bundle file.
Via JavaScript
Call the dropdowns via JavaScript:
Paste this is code after bootstrap.min.js
$('.dropdown-toggle').dropdown();
Also, make sure you include popper.min.js before bootstrap.min.js
Dropdowns are positioned thanks to Popper.js (except when they are contained in a navbar).
Make sure to include the Bootstrap CSS either via the Bootstrap CDN
or download it and link it locally
I used NuGet to install BootStrap 4. I was also having issues with it not displaying the Dropdown on click. It kept throwing an error in jquery base on what the Chrome console was telling me.
I originally had the following
<%-- CSS --%>
<link type="text/css" rel="stylesheet" href="/Content/bootstrap.css" />
<%-- JS --%>
<script type="text/javascript" src="/Scripts/jquery-3.3.1.min.js"></script>
<script type="text/javascript" src="/Scripts/bootstrap.min.js"></script>
But I changed it to use the bundled version instead and it started to work
<%-- CSS --%>
<link type="text/css" rel="stylesheet" href="/Content/bootstrap.css" />
<%-- JS --%>
<script type="text/javascript" src="/Scripts/jquery-3.3.1.min.js"></script>
<script type="text/javascript" src="/Scripts/bootstrap.bundle.min.js"></script>
add this line of code to the end of the body tag
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.0.2/dist/js/bootstrap.bundle.min.js" integrity="sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM" crossorigin="anonymous"></script>
A simple answer is to replace this line:
<script type="text/javascript" src="your_directory/bootstrap.min.js"></script>
for this other:
<script type="text/javascript" src="your_directory/bootstrap.bundle.min.js"></script>
This is my solution
I just downloaded jquery's latest version from their official website and then added it as a js file in my project folder and then to my HTML file. After that it was working fine for me
You need to enqueue the script bootstrap.js or bootstrap.min.js. I had the same problem with bootstrap 4.5.3 and the menu worked when I enqueued one of the above scripts. It can be either.
It needs to be /bootstrap.js, not /bootstrap.min.js.

This question already has answers here:
Navbar dropdown (collapse) is not working in Bootstrap 5
(11 answers)
Closed 2 years ago.
When loading Bootstrap 4.5.3 via the CDN bundle:
<script src="https://cdn.jsdelivr.net/npm/bootstrap#4.5.3/dist/js/bootstrap.bundle.min.js" integrity="sha384-ho+j7jyWK8fNQe+A12Hb8AhRq26LrZ/JpcUGGOn+Y7RsweNrtN/tE3MoK7ZeZDyx" crossorigin="anonymous"></script>
the following dropdown works great:
<!-- Nav Item - Pages Collapse Menu -->
<li class="nav-item">
<a class="nav-link collapsed" href="#" data-toggle="collapse" data-target="#collapseTwo"
aria-expanded="true" aria-controls="collapseTwo">
<span>AAAA</span>
</a>
<div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordionSidebar">
<div class="bg-white py-2 collapse-inner rounded">
<h6 class="collapse-header">BBBB</h6>
<a class="collapse-item" href="CCCC.html">CCCC</a>
<a class="collapse-item" href="DDDD.html">DDDD</a>
</div>
</div>
</li>
However, when I try to upgrade the Bootstrap verson to 5.0.0 via the CDN bundle:
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.0.0-beta1/dist/js/bootstrap.bundle.min.js" integrity="sha384-ygbV9kiqUc6oa4msXn9868pTtWMgiQaeYH7/t7LECLbyPA2x65Kgf80OJFdroafW" crossorigin="anonymous"></script>
Then the dropdown is no longer clickable. Why is this please?
FYI, I am using a clean install of the theme https://startbootstrap.com/theme/sb-admin-2 (source code available on GitHub: https://github.com/startbootstrap/startbootstrap-sb-admin-2), the index.html. Originally, it mentioned:
<!-- Bootstrap core JavaScript-->
<script src="vendor/jquery/jquery.min.js"></script>
<script src="vendor/bootstrap/js/bootstrap.bundle.min.js"></script>
But I noted the version of the /bootstrap.bundle.min.js (4.5.3) and it still worked without problems via the Bootstrap 4.5.3 CDN bundle, as described above.
That is, everything worked great if using:
<!-- Bootstrap core JavaScript-->
<script src="vendor/jquery/jquery.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap#4.5.3/dist/js/bootstrap.bundle.min.js" integrity="sha384-ho+j7jyWK8fNQe+A12Hb8AhRq26LrZ/JpcUGGOn+Y7RsweNrtN/tE3MoK7ZeZDyx" crossorigin="anonymous"></script>
I did not make any other changes to any of the cleanly installed files (see GitHub repository above), other than that last line, and everything kept working.
Then, subsequently, the only change I made, somehow destroying the dropdown, is that I changed that last line into the following (to upgrade to Bootstrap 5.0.0):
<!-- Bootstrap core JavaScript-->
<script src="vendor/jquery/jquery.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.0.0-beta1/dist/js/bootstrap.bundle.min.js" integrity="sha384-ygbV9kiqUc6oa4msXn9868pTtWMgiQaeYH7/t7LECLbyPA2x65Kgf80OJFdroafW" crossorigin="anonymous"></script>
Why does this destroys the dropdown links? What tool can I use to troubleshoot this? I don't see any errors in my Firefox Developer Console.

If you change the last script line, to upgrade to Bootstrap 5.0.0, then the collapsing does no longer work:
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.0.0-beta1/dist/js/bootstrap.bundle.min.js" integrity="sha384-ygbV9kiqUc6oa4msXn9868pTtWMgiQaeYH7/t7LECLbyPA2x65Kgf80OJFdroafW" crossorigin="anonymous"></script>
Any help to make me understand a bit more how to port this code to Bootsrap 5, would be greatly appreciated. Do I even need JQuery for this?
Bootstrap 5 doesn't require jQuery, but you can still use it.
If you compare your code to the docs for Collapse you can see that here was an attribute name change from data-toggle to data-bs-toggle for Bootstrap 5. Also, anchors use the href attribute to set the target, not a data attribute. If you fix those things it works.

I have been trying to use bootstrap(4) to creat a website. I got stuck at creating menu with dropdown lists. I cannot make it work, I even tried copying exact code of the docs for bootstrap and it still doesnt work. I have checked and rechecked paths for bootstrap css and js and I really dont know how to make it work.
While at it, can I use bootstrap to create dropdown lists inside dropside lists? It is for Menu purposes.
bootstrap docs, w3schools and other websites. even copying exact code makes no difference, the button doesnt work

In the above code there are two different parts of code both for similar button. First doesnt work at all. second does, but in a way that just makes button move to right and the 3 other buttons appear on left. unable to change it at all. I would expect the dropdown come directly underneath the button as per docs.
I think you're importing your scripts in the wrong order.
Try putting the jquery script tag first, then the popper script, then you Bootstrap scripts.
And to answer your subsidiary question, it is absolutely possible to put a dropdown into a dropdown.
I am trying to implement a Navbar using Bootstrap 4. Currently, the Navbar correctly collapses when the viewport is shrunk to mobile size. However, when attempting to toggle menu, nothing happens. The jsFiddle example demonstrates this behavior. I have attached the HTML as well.
Steps I have taken:
Removing all custom CSS
Ensuring jQuery link is before Bootstrap JS file
Script tags in the header and the footer
Copy and paste exact examples from Bootstrap Docs (and I get the same behavior)
Ensuring that JS is being used in the Chrome browser
Validated HTML using WC3 validator
And of course, read various posts on SO about this issue but none lead to a resolution

You need to include Popper as per the Getting Started Docs.
Use these for your scripts instead.

Advice: In future, always open the dev inspector console in your browser to find any error messages.
You can also change the bootstrap reference to the bundled version - bootstrap.bundle.min.js - which includes popper.js.

Fiddle: https://jsfiddle.net/smoore4/m2dLp71q/
As #Anand Rockzz correctly points out, you still need to add jQuery before this reference.
This happens when you miss the order of scripts.
You should always include scripts in this order
jquery.js
popper.js
bootstrap.js

This might be helpful ...Since Bootstrap 5 there is a slight change in how collapse works... see code `

Assuming you have indeed downloaded and referenced the files correctly, your code above will work as expected. Note that you have referenced your files relatively, so they must be in a scripts folder at the same level as the file you are trying to run Bootstrap on.
The only required files are jQuery, Tether and Bootstrap.js. popper.js is unnecessary. In addition to the three required JavaScript files, you'll also probably want the Boostrap CSS file as well.
The JavaScript files should be referenced in the following order:
jQuery
Tether
Bootstrap's JavaScript component
It doesn't matter when you load Bootstrap's CSS.
This can be seen working in the following example:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" integrity="sha384-rwoIResjU2yc3z8GV/NPeZWAv56rSmLldC3R/AZzGRnGxQQKnKkoFVhFQhNUwEyJ" crossorigin="anonymous">

<script src="https://cdnjs.cloudflare.com/ajax/libs/tether/1.4.0/js/tether.min.js" integrity="sha384-DztdAPBWPRXSA/3eYEEUWrWCy7G5KFbe8fFjk5JAIxUYHKkDx6Qin1DkWx51bBrb" crossorigin="anonymous"></script>

<div class="col-12">
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">

<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>

Feel free to build from this template.
Hope this helps! :)
I can't find the reason why, when trying to use the navbar button from Bootstrap, it doesn't work.
I think it has something to do with my page loading the jQuery library or something, though I don't understand.
Here is my code. I'll show just the head and navbar parts since I believe there's where the problem lives. Everything else is simple HTML structure:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta charset="UTF-8">
<meta name="viewport" content="initial-scale=1">

Am I missing something? Like loading a library?
Bootstrap does not include jQuery, so you need to add it yourself to make it work. Add it just before your bootstrap.js script.
As per Bootstrap's docs:
jQuery required
Please note that all JavaScript plugins require jQuery
to be included, as shown in the starter template. Consult our
bower.json to see which versions of jQuery are supported.
On top of that, the integrity check fails on your bootstrap.min.js script. To make it work you need to fix that and add at least version 1.9.0 of jQuery:
...
<script src="https://code.jquery.com/jquery-2.2.4.min.js" integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44=" crossorigin="anonymous"></script>
<!--Boostrap jQuery-->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>
...
You should check your bootstrap.css files in the head section, jquery.js before body closing tags, and you should give id to toggled nav same as button data-target.
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
