Why isn't collapse in Bootstrap 5 working from the example?
(2 answers)
Closed 10 months ago.
I'm trying to use collapse in a navbar using Bootstrap. When the collapse control shows and I click it, nothing happens.
I'm sure I put the jQuery and Bootstrap bundle scripts in the right place.
Manually collapsing it in the console using $(".collapse").collapse(); works, though.
This is my entire page, if it helps.

I researched for a little while and found how to fix this here. Turns out, I needed to change the data-toggle and data-target attributes to data-bs-toggle and data-bs-target.
Keep aware that depending on the version of the bootstrap a lot of things also change. For example, ms on bootstrap 5 is the same as ml on bootstrap 4.

I am creating a web, which will have many sub pages and I want to include a NavBar in all of them, I am working with bootstrap 5 and I want to know if there is any way to create a single NavBar and insert it in all the pages so I don't have to update them 1 by one every time I make a change.
I leave here the code of my NavBar:

I have tried to import the code from another file with JavaScript but the format is not correct.
I have already checked these links but I have not been able to make it work:
SO (in spanish)
Lost question
Yes, you can create a separate HTML file for your Navbar and then include it in all the pages where you want to use it. This way, any changes you make to the Navbar will automatically reflect on all the pages where it's included.
To include the Navbar in other pages, you can use JavaScript to load the HTML content of the Navbar file and then insert it into the page. Here's an example:
1. Create a separate file for the Navbar, let's call it navbar.html,
and place your Navbar code in it.
2. On your other pages, add an empty div element where you want to
include the Navbar. For example:
<body>
<div id="navbar"></div>
<!-- rest of your page content -->
</body>
3. Add the following JavaScript code to the bottom of your page, just
before the closing tag:
<script>
// Load the Navbar content
fetch('navbar.html')
.then(response => response.text())
.then(data => {
// Insert the Navbar content into the navbar div
const navbar = document.getElementById('navbar');
navbar.innerHTML = data;
});
</script>
This code uses the Fetch API to load the content of the navbar.html file and then inserts it into the navbar div.
Make sure to replace navbar.html with the correct path to your Navbar file.
With this setup, any changes you make to the Navbar code in the navbar.html file will automatically reflect on all the pages where the Navbar is included.
I have a dropdown menu made in Bootstrap. I implemented a jQuery toggleClass on the dropdown menu icon that changes the icon on click. Normally, it is supposed to show the hamburger icon when the menu is closed, then change to an X icon when the menu is open. But the problem here is that, if the menu is clicked too fast(a double click), the reverse would then be the case(i.e The menu then shows an X icon when closed and a hamburger icon when open). And I dont want that. Here is the code snippet.
$("span.toggler").click(function() {
$("#toggler-icon").toggleClass("fa-bars fa-times");
})

Is there a way I can prevent this?
If you use the right selectors, you can style the toggler icon based on the navbar's state (collapsed or not).

NOTE: My Answer is more about giving you intuition on WHAT the problem is and WHY it's happening. I think #kmoser's suggestion is the best suggestion.
The issue is JavaScript Call Stack is competing with the Render Event Loop creating a race condition which the render events will always loose. But Why?
Render event's travel thru the browsers Event-Loop onto JavaScript's Call Stack. BUT, button clicks travel directly to the Call Stack, skipping the event loop. Which means, button clicks are executed immediately (in most cases: synchronously) while render events are executed asynchronously (most of the time) and thus the render events don't have a chance to be appended to the Call Stack in the order you intended.
Why? Because they typically carryout animations! and animations are always syntactically described with some millisecond delay runtime.
CSS Stylesheet Syntax Example:
animation: .5s linear 1s infinite alternate slidein;
The .5s is an asynchronous side-effect. Therefore it will automatically be put onto the Browsers Event-Loop, and whenever JavaScript's Call-Stack says
Hey event loop, i'm finished with all these button clicks, I'm ready for that animation you're holding!
then it executes the animation by pushing it onto the Call Stack.
In your case, if you looked under-the-hood into Bootstraps CSS files you'd find some animating syntax per my example for the dropdown with the millisecond runtime defined.
The solution?
As #kmoser pointed out, the intended way to accomplish your desired task is to trigger css icon changes (Hamburger to X) based on css actions (animations: dropdown open, dropdown closed), rather than user actions.
Hope that helps.
I have been trying to use bootstrap(4) to creat a website. I got stuck at creating menu with dropdown lists. I cannot make it work, I even tried copying exact code of the docs for bootstrap and it still doesnt work. I have checked and rechecked paths for bootstrap css and js and I really dont know how to make it work.
While at it, can I use bootstrap to create dropdown lists inside dropside lists? It is for Menu purposes.
bootstrap docs, w3schools and other websites. even copying exact code makes no difference, the button doesnt work

In the above code there are two different parts of code both for similar button. First doesnt work at all. second does, but in a way that just makes button move to right and the 3 other buttons appear on left. unable to change it at all. I would expect the dropdown come directly underneath the button as per docs.
I think you're importing your scripts in the wrong order.
Try putting the jquery script tag first, then the popper script, then you Bootstrap scripts.
And to answer your subsidiary question, it is absolutely possible to put a dropdown into a dropdown.
I can't find the reason why, when trying to use the navbar button from Bootstrap, it doesn't work.
I think it has something to do with my page loading the jQuery library or something, though I don't understand.
Here is my code. I'll show just the head and navbar parts since I believe there's where the problem lives. Everything else is simple HTML structure:

Am I missing something? Like loading a library?
Bootstrap does not include jQuery, so you need to add it yourself to make it work. Add it just before your bootstrap.js script.
As per Bootstrap's docs:
jQuery required
Please note that all JavaScript plugins require jQuery
to be included, as shown in the starter template. Consult our
bower.json to see which versions of jQuery are supported.
On top of that, the integrity check fails on your bootstrap.min.js script. To make it work you need to fix that and add at least version 1.9.0 of jQuery:
...
<script src="https://code.jquery.com/jquery-2.2.4.min.js" integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44=" crossorigin="anonymous"></script>
<!--Boostrap jQuery-->
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>
...
You should check your bootstrap.css files in the head section, jquery.js before body closing tags, and you should give id to toggled nav same as button data-target.
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
I am working on a project using the bootstrap and in starting the fixed navigation on top I have found that it is hiding the links (ie. Home, Account, Logoff), presumably collapsing them. Because when i shrink it down and get the toggle it will display them after i initiate it. When I remove the .collapse from just below the first comment it displays the links. However then it will not collapse on resizing. How do I get the top nav links to show and still have the toggle work? Note: All of the file paths to the css and js are correct directories

Turns out it was because I was trying to combine js and css from both Bootstrap 2 and 3. Once I got everything on the same playing field it works just fine.
