I'm trying to create a navigation bar with Bootstrap. I have imported the skeleton from the Bootstrap official website with all the necessary components, however, the hamburger menu doesn't seem to open up properly.
Navigation bar has also been imported directly from Bootstrap website as well.
I've been searching for the solution for long period of time, but cannot seem to find the solution.

It seems like you have given some classes of bootstap 4, while you have been imported cdn of bootstrap 5.
<button
class="navbar-toggler"
type="button"
data-bs-toggle="collapse"
data-bs-target="#navbarNavDropdown"
aria-controls="navbarNavDropdown"
aria-expanded="false"
aria-label="Toggle navigation"
>
<span class="navbar-toggler-icon"></span>
</button>
replace your button with the above code. it should work.
Can you please check the below code? Hope it will work for you.

I copied and pasted this straight from the bootstrap website. I am new to html and bootstrap. Pls help. I think if u copy paste this code to a html file, and then open it in a small browser window and press the toggle button, u will see what i mean.
This is because your bootstrap's js has 3.4.1 and css has 4.0.0. Please add same versions.

A few things:
You're missing some necessities. Move the <nav> into the <body> (not in the <head>). You then need these added right before the </body>:

What am I doing wrong?
I have added all required libraries..
I'm trying to learn Bootstrap 4 Navbar and getting it to work with a ASP.NET Webform using framework 4.7.2 (Visual Studio 2013). I copied code from Bootstraps own website and place it in the master Page. In the < HEAD > I have:

The page renders fine as per the Bootstrap example but the dropdown doesn't do anything. Yet, if I create a .HTML page and paste the exact same code, it works fine. So i'm wondering why this code wouldn't work in a WebForm?
I'm using the later Bootstrap.JS (4.1.3), Latest jQuery (3.1.1) and the latest popper.js.
Thanks.
I found that the following worked i.e just by single click on the text Dropdown, the menu opens. Using your code, it opened but by clicking the text twice.
I used the following code to test this scenario. Note that bootstrap.bundle.min.js inlcudes popper.js as well as bootstrap.min.js, so there is no need to include these JavaScript files. This may be why its not working as expected.
You can take a look at following documentation for specifics about bootstrap.bundle.min.js: Bootstrap Bundle JavaScript Includes what

I have added the following navbar with the new bootstrap 4 version. but it doesn't show anything below the nav bar as well. The text inserted after the nav, also it doesn't take the width and height properties if an external css file is used to give css to the image inserted below. Any idea why this is happening??
