I am trying to add a navbar to this website, but for some reason it is not functioning how I thought it would. The main problem I am trying to solve is getting the dropdown menu to actually display the list. It visually looks like the menu is already expanded, but I don't know if that has anything to do with why it is not working. Currently, the collapsed version will open from the hamburger menu only because of the CSS I added. Without the CSS, that navbar will expand, but immediately collapse again. Things I have tried:
I have tried to switch the order that I include Bootstrap.js/css and jQuery, but that has no effect on it.
I have also tried to switch versions because I am not sure what is compatible with what, but that has not been successful.
The one thing that did work was using an old version of bootstrap, but I would like to use 4.0 or higher if that is possible.
I would appreciate it is someone could help me figure out why this is not working. Thanks!

That's because your bootstrap.js is version 3.3.7, and this is not how you implement sub-menu (on bootstrap 3). Although, If you're using bootstrap 4 already, you should consider updating your bootstrap.js to version 4.0.0 (And you should use the same versions of bootstrap.js and bootstrap.css to avoid unexepected bugs (like you just had).

I have copied every links which I have to. Also, copied the same code for the toggler which is in the bootstrap v5.1. The menu opens when I click on the toggler but it does not collapse if I click on it again. The code is working fine in bootstrap document but not in browser. Below is my code.

I think it was a problem of script import.

This question already has answers here:
Bootstrap 5 navbar align items right
(13 answers)
Navbar dropdown (collapse) is not working in Bootstrap 5
(11 answers)
Closed 1 year ago.
I am trying out Bootstrap for the first time, and it dose not seems like it is working as it should. I am trying out an a example. I will make the navbar links go to the right, and when the screen gose smaller it will be an hamburger menu (also on the right side). When i am trying this, the links gose not to the right (i tryd mr-auto and ml-auto for the ul), but when the screen go smaller, it dose form as a hamburger, but it dos not go to the right and it dose not open when i click it. So that is a big issue. Nothinh happens when i click the hamburger menu.
Am i doing something wrong with my links or code? I did download the bootstrap map's js and css and added to the project and linkin to it.

On a large screen, it looks like this.
You can also change the container and expand classes according to your needs.
this is my code on bootstrap for navbar but it is not getting fit proper as u can see in png
it is coming at the center of the page i want it to cover the whole page .enter image description here
Brand
<div class="collapse navbar-collapse justify-content-between" id="navbarCollapse">
<div class="navbar-nav">
Home
Profile
<div class="nav-item dropdown">
Messages
<div class="dropdown-menu">
Inbox
Sent
Drafts
</div>
</div>
</div>
<form class="form-inline">
<div class="input-group">
<input type="text" class="form-control" placeholder="Search" />
<div class="input-group-append">
<button type="button" class="btn btn-secondary"><i class="fa fa-search"></i></button>
</div>
</div>
</form>
<div class="navbar-nav">
Login
</div>
</div>
</nav>
Here is an example.
In the example below I use container-fluid with a margin of 0 and padding of 0.
(You can do it without container-fluid wrapping your navbar, it is your choice for the sake of an example I will leave it in the snippet.)
Then if you want to put content inside of the navbar inside of the container. You can put div with a class of a container after starting the nav tag.

So, I just copied a code snippet for the navbar form from bootswatch and directly imported the required JQuery, bootstrap css and js files as you can see in the snippet below. It is being responsive when the browser is resized but when I click the button to get the dropdown menu of the navbar it glitches and doesn't go down and stay there but toggles back on its own.
No tweaks or changes has been made in the code and it works fine on the bootswatch website but it doesn't here. Can anyone explain why and give a fix?

The problem is in the very thing you mentioned you changed; the Bootstrap and jQuery files. You're using the jQuery from Bootstrap 3.3.7, and the CSS from Bootstrap 4, which have conflicts. Also note that Bootstrap 4 additionally needs Popper.js.
Changing both Bootstrap files to use Bootstrap 4 (and including Popper) fixes this problem:

Hope this helps! :)
That is because bootswatch is using bootstrap 4.0 beta rather than 3.and for bootstrap4 you will need popper.js
see the demo below

<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.13.0/umd/popper.js"></script>

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/js/bootstrap.min.js"></script>
<nav class="navbar navbar-expand-lg navbar-dark bg-primary">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor01" aria-controls="navbarColor01" aria-expanded="false" aria-label="Toggle navigation" style="">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarColor01">

</form>
</div>

EDIT
While trying to include popper.js keep in mind to use only the umd specific directory, not esm or any other. See this previous issue for details
Right now I'm going to through the Bootstrap material and trying to learn how to use their content with a jinja2 file I'm prepping up for a django project. When I tried copy and pasting their example code
(specifically this example http://getbootstrap.com/docs/4.0/components/navbar/)
into my project it seemed to be working however none of the dropdown elements are responsive and when it enters mobile it wont expand. This was with me using my local css and js files, so I thought I'll use the recommended cdn files on the Jinja website. Now it is functional, but it is stuck in mobile mode. How should I resolve this problem?
