I followed the tutorial on official site of Bootstrap, and at this page is a simple example how to use tabs with dropdowns menu bootstrap example
And it works on this page, but when I add this code to codepen or to my project it doesn't work. All bootstrap dependencies are added. But I noticed some weird thing that when I use previous version, such as 3.4.0, it works fine, without issues, but with new version 4.3.1 - dropdown menu doesn't expanding. Maybe I'm doing something wrong.
This example from the bootstrap official site in my codepen page, please follow this link and give me some advices. Codepen example.
<ul class="nav nav-tabs" id="myTab" role="tablist">
<li class="nav-item">
<a class="nav-link active" id="home-tab" data-toggle="tab" href="#logs"
role="tab" aria-controls="logs" aria-selected="true">
Logs
</a>
</li>
<li class="nav-item">
<a class="nav-link" id="profile-tab" data-toggle="tab" href="#scriptMessage"
role="tab" aria-controls="scriptMessage" aria-selected="false">
Scripts/Messages
</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Menu</a>
<div class="dropdown-menu">
<a class="dropdown-item" href="#">Submenu 1-1</a>
<a class="dropdown-item" href="#">Submenu 1-2</a>
<a class="dropdown-item" href="#">Submenu 1-3</a>
</div>
</li>
</ul>
Thank you guys for your help!. I forgot to add one more dependency, Popper.js or Bootstrap Bundle js (Popper is already included), to my project, but now it works correctly.
Bootstrap has its own JavaScript for some functionalities:
Go to this link
Copy the 'Complete JavaScript Bundle' link
Paste that link to your code pen like this: Pen Settings screenshot (You must add it AFTER JQuery)
The bundle already comes with the needed functions for Bootstrap. You just have to add that and JQuery.
You can see which Js dependencies are needed for each bootstrap components and more info on how to add those dependencies to your project here
your code is working fine use the links like below or check your updated codepen here

some of bootstrap component need javascript code for actions. In your case you need to put default js bundle before closing body tag.

for reference use https://getbootstrap.com/docs/4.3/getting-started/introduction/#js
You missed the jQuery library.

This is the code I have been trying to add a dropdown button to using Bootstrap 5, I was able to successfully add the element Projects as a toggle button but it is not working, when pressed it just refreshes the webpage.
Rest of the navbar working just fine
Even the brand element that is set to reset to home webpage works fine
Add href="#" and also add data-target="dropdown" property to <a> tag
<ul class="navbar-nav ms-auto">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="projectsButton" role="button" data-bs-toggle="dropdown"
data-target="dropdown" aria-expanded="false">
Projects
</a>
<ul class="dropdown-menu" aria-labelledby="projectsButton">
<li><a class="dropdown-item" href="#">Action</a></li>
<li><a class="dropdown-item" href="#">Another action</a></li>
<li><a class="dropdown-item" href="#">Something else here</a></li>
</ul>

I am quite desperate, I checked every similar questions on stackoverflow and tried many solutions found on google but in vain... I'm really unable to find a working solution to my problem.
I am developping a site with Bootstrap 4 and I have a navbar. When I click on one of the nav-link I want it to have the "active" class, while others stay normal.
I might not select the right elements or use wrong jquery/javascript code.
The navbar html code (1) is in a separate header.html file that I load with JS at the beginning of the html page (2):
(1)
<nav class="navbar navbar-expand-lg navbar-dark bg-dark fixed-top ml-auto">
<div class="container">
<a class="navbar-brand" href="../index.html#"><img src="../images/DSIMB.svg" alt=""></a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Team</a>
<div class="dropdown-menu" aria-labelledby="dropdown01">
<a class="dropdown-item" href="members.html#">Members</a>
<a class="dropdown-item" href="publications.html#">Publications</a>
<a class="dropdown-item" href="teaching.html#">Teaching</a>
</div>
</li>
<li class="nav-item">
<a class="nav-link" href="web_tools.html#">Web Tools</a>
</li>
<li class="nav-item">
<a class="nav-link" href="research.html#">Research</a>
</li>
<li class="nav-item">
<a class="nav-link" href="infrastructures.html#">Infrastructures</a>
</li>
<li class="nav-item">
<a class="nav-link" href="news.html#">News</a>
</li>
<li class="nav-item">
<a class="nav-link" href="contacts.html#">Contacts</a>
</li>
</ul>
</div>
</div>
</nav>
(2)
<script>
$(function() {
$("#header").load("./header.html");
});
</script>
Here is the JS I put at the end of the html page just before the </body> tag:
<script>
$('.navbar .nav-item .navlink').click(function() {
$('.navbar .nav-item').removeClass('active');
$(this).addClass('active');
})
</script>
And here the active css class I want to set to the active nav-link:
.navbar .nav-item > .nav-link.active {
color:white;
font-weight: 700;
}
Please tell me what I am doing wrong...
UPDATE
I put here the solution I found thanks to a simple snippet (that I adapted to my code) taken from this site which #NmiDev kindly pointed to me.
I add my custom active class to the link in the navbar targeted thanks to href / location parsing:
$("#header").load("./header.html", function(){
$('a[href="' + location.pathname.split("/")[2] + '"]').addClass("active-nav");
});
Here a snippet.
Hope it's help you.

It's seems that you don't need to override the css active class. White is the default behavior.
I'm very new to Bootstrap (and front end dev in general). I'm trying to get a Bootstrap4 navbar to work. I've essentially copied and pasted code from the bootstrap website, but I can't get it working.
When I shrink the page, the menu does collapse as it should. However, when I click on the collapsed menu, nothing happens. Also, on the expanded menu, nothing happens when I click the dropdown menu.
I've verified path to the boostrap.min.js is correct.
I'm loading this page file via "file://" in my browser, not off a server. I don't know if that could be a problem, but I wouldn't think so. Anyway, here is the code:
<!DOCTYPE html>

I'm sure it's something simple (I feel like the javascript isn't loading, for some reason), but I can't figure it out. Anybody see anything obvious?
Edit: I should also note that I don't see any Javascript errors in console, and I'm not sure I'm checking correctly, but it doesn't look like there are event listeners registered for the button (so nothing should happen when I click it).
Edit2: I just started a quick web server to load this from. None of the javascript files are being requested from the server. The main problem seems to be with the loading of the javascript files. Paths are correct, though.
Solved: The problem was I was using href for my script tags, instead of src. Changed to src and everything is working as expected.
Try the following code below for BootStrap4 Starter template. It will run anywhere just double click on the file. All source included from CDN.

The attributes for the script tags were all wrong. I had href. It should be src. I fixed it and everything is working now.

How to make hover effect instead of click in bootstrap dropdown menu?
Previous answers don't contain jquery code that you can just past into you own script and get a great result. Apart from this, previous answers wrote for old version bootstrap, and for bootstrap 4 they don't work. For example this question too old, + current question contain a small piece of code which will work for all.

You could add a mouse over event using jquery and apply the same styles and properties that the click event adds..
$( ".dropdown-menu" ).css('margin-top',0);
$( ".dropdown" )
.mouseover(function() {
$( this ).addClass('show').attr('aria-expanded',"true");
$( this ).find('.dropdown-menu').addClass('show');
})
.mouseout(function() {
$( this ).removeClass('show').attr('aria-expanded',"false");
$( this ).find('.dropdown-menu').removeClass('show');
});

A work around to prevent the menu being hidden after the mouse out is to set margin-top:0 to the dropdown-menu
Just triggering the click event on hover() will do the trick:
$('.nav-link').hover(function() {
$(this).trigger('click');
}, function() { });

I've got problem with navbar dropdown. It show up properly but when I try to expand category doesn't happen anything. Also copied templary straight from Bootstrap's documentation. Doesn't seem like I can figure it out what is wrong by myself.

And here is my directory: Directory
As you can see in your console, the requiered js could not be loaded.
So check your paths for the files that you can see in the console with an error of 404. Your .css files are getting loaded from /src/css/ but your js files from /js/ it should be src/js. You may want to check that... . I´m affraid no one can help you find your files on your webserver!
