The .navbar-toggler-icon does not appear on the .navbar-toggler button when the menu is collapsed for mobile responsiveness.
I want the Navbar button above the left
Use this body code only...... for your bootstrap.

I tried to mobile view and the navbar toggler is not showing items
Your toggle button has incorrect attributes. Change data-toggle="collapse" to data-bs-toggle="collapse" and change data-target="#navbarSupportedContent" to data-bs-target="#navbarSupportedContent".
Working snippet below:
<button class="navbar-toggler ms-auto" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">

I am new to Bootstrap and am trying to build a three-column navigation menu with the nav-links centered in the middle. I could build this in five minutes using grids or flexbox but for the life of me, I can't center the nav-links!!! picture for reference.
<nav class="navbar navbar-expand-lg navbar-light bg-light">

<div class="collapse navbar-collapse" id="navbarSupportedContent">

You can do it in two ways
By adding mx-auto class to ul tag i.e
<ul class="col-md-3 navbar-nav mx-auto">
By adding justify-content-center to the collapse div
<div class="collapse navbar-collapse justify-content-center" id="navbarSupportedContent">
Hope it work for you :)
I've run into a small issue whilst using Bootstrap. Every time I expand my menu (burger icon) it doesn't collapse after I attempt to close it. Could you please let me know where I've gone wrong & what I could do to avoid this issue in the future, thank you.

I try it and works perfectly. Make sure you are using correct bootstrap version.
I am new to this so please bear with me. I copied this navbar code from Bootstrap and tweaked it to fit my code.
I have a dropdown list with three dropdown items. I want the user to have two options. They can go to the portfolio page and find the links there or they can use the dropdown menu.
The link to the portfolio page does not work when the last script that contains bootstrap.min.js is in the code. Not sure why this is not working. If I take out the dropdown and make it a regular link it goes to the portfolio page. Here is my code:

There's nothing wrong with min.js library. Only you should follow perfect body layout and syntax. It's better to always keep your <script> files before </body> tag ends. End you forgot write some elements inside the body instead you wrote them outside body tag. I just adjusted some of your code. Check it once.

<h3>Collapsible Navbar</h3>
<p>In this example, the navigation bar is hidden on small screens and replaced by a button in the top right corner (try to re-size this window).</p>
<p>Only when the button is clicked, the navigation bar will be displayed.</p>
<p>Tip: You can also remove the .navbar-expand-md class to ALWAYS hide navbar links and display the toggler button.</p>
