I was creating a dropdown at 'Menubar'. I am using Bootstrap 5.1 to do that. This is an 'ASP.NET Core 6 MVC' project. It'ss also a partial view. The exact code is as following:
<li class="nav-item dropdown show">
<a class="dropdown-toggle nav-link text-dark" href="#" data-toggle="dropdown">Admin</a>
<div class="dropdown-menu">
<a class="dropdown-item">Categories</a>
<a class="dropdown-item">Media Types</a>
</div>
</li>
But whenever I click on this link the dropdown doesn't toggle. If someone can point out the problem that would be very helpful. The reference video is attached here
The above answer are all wrong. I have watched your video, and the reason behine is your code is using bootstrap-4, instead of bootstrap-5.
I have tested your code with bootstrap-4 starter template, and now it works.

Check the starter template by here.
If you sure your whole ASP.NET Core MVC Bootstrap's version is 5.1, your code won't work.
You have a typo here:
Before
<a class="dropdown-item">>Categories</a>
After
<a class="dropdown-item">Categories</a>
Update
Adding to the typo you had, like #seantsang94121 said the other problem here is that you are using this code in bootstrap 5 and it only works in bootstrap 4 as his example shown on his answer -> Answer
you need those:

I'm trying to make the inside of the color white with the CSS file, unfortunately it doesn't seem to want to change even though I have specified it which should override the bootstrap. Thanks for taking your time to look at this problem!
Use !important attribute to override bootstrap. Also you have added the anchor tag wrong in css. The colora class is applied to anchor tag. However, your CSS denotes that find anchor tag inside colora class which is not present. Remove the anchor from the css and it will work. Below is your working code example.
.colora,.colora:visited {
color: #fff !important;
text-decoration: none !important;
}

Your css is referencing an a element that is the child of an element with a class of colora. There is no such element.
I think you want
a.colora,a.colora:visited {
but I can only guess.
a.colora,a.colora:visited {
color: rgb(255, 255, 250);
text-decoration: none;
}

Got it working, the problem was apparently I needed to rename the static which I named template, to static. Also I had to specify the file location instead of using the url_for method. Don't know why it worked but that would be the finalized code.
I was trying to make dropdown button via data attributes using bootstrap, but when I click on button nothing happen.
I follow official documentation, even directly copy example but the button is not opening the menu. There is test page:

Can someone tell me what is missing or what I doing wrong?
In the official page of Bootstrap They Mentioned you have to load jquery first then pooper js then lastly their javascript You have mistyped the order
Their official example
<!-- jQuery first, then Popper.js, then Bootstrap JS -->
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

also I would suggest using the minified version of jquery (not the slim) if you are planning on using it
According to the documentation:
jQuery must come first, then Popper.js, and then our JavaScript plugins.
So all you have to do is change the order of your script tags.
Like so:
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
JQuery,
Popper.js,
Bootstrap.js
That should do the trick
You linked the scripts into your project in the wrong order, let's fix that:

So I was wondering how to change the H1 font-family in Bootstrap 4? Can't seem to get it right.. I'm kind of new to this bootstrap thing, so I followed a tutorial on Youtube, but they didn't explain how to change the font-family..
See the code here: (I deleted my css, because it didn't work at all and I honestly didn't even know what I was doing)
<div class="container">
<h1 class="display-2">Hello, World!</h1>

You are loading the style sheets in the wrong order - first needs to be the Bootstrap css and then yours (assuming that stylesheet.css is where you are setting the alternate font-family on the h1) - so that your can overwrite the BS styles- AFTER loading bootstrap. The following shows the order the stylesheets should be loaded :
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css" integrity="sha384-PsH8R72JQ3SOdhVi3uxftmaW6Vc51MKb0q5P2rRUpPvrszuE4W1povHYgTpBfshb" crossorigin="anonymous">
<link rel="stylesheet" href="stylesheet.css">
As a demo of the alternate font family:
The following shows 2 h1's - and I am loading in an alternate font family
.alternate-font {
font-family:"Montserrat"
}
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css" integrity="sha384-PsH8R72JQ3SOdhVi3uxftmaW6Vc51MKb0q5P2rRUpPvrszuE4W1povHYgTpBfshb" crossorigin="anonymous">
<link href="https://fonts.googleapis.com/css?family=Montserrat:300,400,500,600" rel="stylesheet">-
<h1>This is a h1 using standard bootstrap h1 font-family</h1>
<h1 class="alternate-font">This is a h1 using Montserrat font-family</h1>

I have an angular2 website that uses bootstrap and it worked perfectly fine for 2 months. Today many of bootstrap's features just disappeared. Below is the image - the white stripe on the top is where the nav bar used to be - the navbar's title is still there, but color and other items, like login, register etc are not visible (or not there anymore). I've tried to change bootstrap 3.3.7 to 4beta, but the result is still the same...
That's how it looked before:

I'm back in business)) the problem was with this code:
<link rel="stylesheet" href="https://bootswatch.com/flatly/bootstrap.css">
I switched to standard bootstrap and it now works:
