I read the Bootstrap documentation about carousel, also tried all available "example" in the search engine. Unfortunately, there is no way I can achieve such an effect.
I try get effect and add name every slider as tab. Can anyone little help me on how to add extra tabs like this? I paste example photo here:


You are right, Bootstrap does not support carousel slider tabs out of the box. But because Bootstrap uses the data attributes data-bs-target and data-bs-slide-to for the indicators you can apply them to other elements.
For example, apply them on a list outside of the carousel, which are the slider tabs:
<ul class="custom-indicators">
<li data-bs-target="#carouselExampleIndicators" data-bs-slide-to="0" aria-label="Slide 1">
Slide 1
</li>
...
</ul>
The slider tabs in the snippet has more classes to position everything using a row with four columns col. Simply clicking on a <li> element will already set the carousel to that slide index (0).
To style the active slider tab use JavaScript by toggling a class on it, like .active and style it using CSS.
Here are two basic examples, using Jquery or plain Javascript.
Solution with Jquery
Lucky for us, Bootstrap’s carousel class exposes events for hooking into carousel functionality, like slide.bs.carousel:
$('#carouselExampleIndicators').on('slide.bs.carousel', event => { ... });
This function will fire whenever the carousel transitions to another slide. Inside access the event property to, which holds the index of the next slide. Then toggle the active class:
const nextSlide = event.to;
$('.custom-indicators li').removeClass('active');
$('.custom-indicators li[data-bs-slide-to=' + nextSlide + ']').addClass('active');
Now apply some custom CSS to style the tabs, and that's. Here's the complete basic example of custom indicators that can be styled:
$('#carouselExampleIndicators').on('slide.bs.carousel', event => {
const nextSlide = event.to;
$('.custom-indicators li').removeClass('active');
$('.custom-indicators li[data-bs-slide-to=' + nextSlide + ']').addClass('active');
});
.custom-indicators li {
border-top: 3px solid transparent;
}
.custom-indicators li.active {
color: black;
font-weight: bold;
border-top: 3px solid black;
}

Slide 4
</li>
</ul>

</div>
Solution with JavaScript
Here's a solution that uses plain Javascript to accomplish the same thing. It loops over all slider tabs removing the class active and applies it on the slider tab that has the index (data-bs-slide-to="?") of the next slide.
var carousel = document.querySelector('#carouselExampleIndicators');
carousel.addEventListener('slide.bs.carousel', event => {
var nextSlide = event.to;
var customIndicators = document.querySelectorAll('.custom-indicators li');
for (var i = 0; i < customIndicators.length; i++) {
customIndicators[i].classList.remove('active');
}
document.querySelector('.custom-indicators li[data-bs-slide-to="' + nextSlide + '"]').classList.add('active');
});
.custom-indicators li {
border-top: 3px solid transparent;
}
.custom-indicators li.active {
color: black;
font-weight: bold;
border-top: 3px solid black;
}

Bootstrap 5 Carousel showing only control and not contents

I am working on an HTML site and I am using the bootstrap 5 frameworks.
MY GOAL is to add bootstrap 5 Carousel in my section next to an image, like show in this image.
[https://imgur.com/a/JSvH2nw]
I have directly copied Carousel code from bootstrap docs here is the link
https://getbootstrap.com/docs/5.1/components/carousel/#slides-only
But for some reason, the Carousel is not showing any content it is only showing controls and slider buttons like this

You need to replace ... with actual image link
where the img tag is in your html code
<img src="..." class="d-block w-100" alt="...">
like this :
<img src="..." class="d-block w-100" alt="...">
Update:
if you want carousel without image you can do that by following:
<div class="carousel-inner">
<div class="carousel-item active" data-bs-interval="10000" >
<!-- <img src="https://cdn.pixabay.com/photo/2015/10/29/14/38/web-1012467__340.jpg" class="d-block w-100" alt="..."> -->
<div class="">
<h5>First slide label</h5>
<p>Some representative placeholder content for the first slide.</p>
</div>
</div>
<div class="carousel-item" data-bs-interval="2000">
<!-- <img src="https://img.freepik.com/free-vector/abstract-dotted-banner-background_1035-18160.jpg?size=626&ext=jpg" class="d-block w-100" alt="..."> -->
<div class="">
<h5>Second slide label</h5>
<p>Some representative placeholder content for the second slide.</p>
</div>
</div>
<div class="carousel-item">
<!-- <img src="https://static.vecteezy.com/system/resources/thumbnails/001/234/358/small/modern-blue-halftone-banner-background.jpg" class="d-block w-100" alt="..."> -->
<div class="">
<h5>Third slide label</h5>
<p>Some representative placeholder content for the third slide.</p>
</div>
</div>
</div>
Simple trick: just remove the img tags from the html and remove carousel-caption class from the caption text div
alternatively you can use owl carousel to create beautiful carousels just like what you want
Here is a jsbin link i created with your code.

Note that the image address in your code should be changed to your own image address.

Angular 13 with Boostrap 5 Carousel not working on build version

I am trying to use Bootstrap 5 Carousel slide in my Angular 13 project. Everything works fine in development with ng serve, but once I build a production version ng build it's not working, the carousel is missing slide effect, next image appears immediately under the sliding away image.

dependencies necessary for Bootstrap's carousel

What JavaScript dependencies needs to be included when I want to use just the Carousel functionality? That means I don't want to use bootstrap.js, just JS necessary for Carousel (carousel.js, ...).
The setup code (with regards to the docs) is:
var myCarousel = document.querySelector('#myCarousel')
var carousel = new bootstrap.Carousel(myCarousel)
But obviously the Bootstrap 5 part is missing, as I get the error:
(index):511 Uncaught ReferenceError: bootstrap is not defined
I can't seem to find this info in Bootstrap's official docs and anywhere else.

I does not give the error if you include bootstrap bundle for instance.

Scrolling is locking on mobile devices

I got an issue with my website when I am trying to scroll website on mobile devices sometimes its locking and even when you slide finger on device website is not moving properly. On desktop scrolling working fine. I tried to find the solution but cant figure out what is wrong.
You can test it with developers tools on 375 px resolution or in mobile devices here
Bootstrap 4 template: NOW UI Kit by Creative Tim
I thought problem is with cookie script but when I disable it by commenting in HTML problem is not solving. I tried to comment parts of my JS file but still not working.
There is my JS Script:
var selectedClass = "";
$(".filter").click(function () {
selectedClass = $(this).attr("data-rel");
$("#gallery").fadeTo(100, 0.1);
$("#gallery div").not("." + selectedClass).fadeOut().removeClass('animation');
setTimeout(function () {
$("." + selectedClass).fadeIn().addClass('animation');
$("#gallery").fadeTo(300, 1);
}, 300);
});
$( "#scrollDown" ).click(function() {
$( "html, body" ).animate({
scrollTop: 600
}, 600, function() {
// Animation complete.
});
});
//Gallery Animations
baguetteBox.run('.grid-gallery', { animation: 'slideIn' });
//Anchor Function
function scrollToAnchor(aid){
let aTag = $("a[name='"+ aid +"']");
$('html,body').animate({scrollTop: aTag.offset().top}, 900);
}
//Menu Anchors Animations
$("#lexuslink").click(function() {
scrollToAnchor('lexus');
});
$("#fiatlink").click(function() {
scrollToAnchor('fiat');
});
$("#merclink").click(function() {
scrollToAnchor('merc');
});
$("#homelink").click(function(){
$('html, body').animate({scrollTop: 0}, 900)
});
$("a").on('click', function(event) {
// Make sure this.hash has a value before overriding default behavior
if (this.hash !== "") {
// Prevent default anchor click behavior
event.preventDefault();
// Store hash
let hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll
// The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
$('html, body').animate({
scrollTop: $(hash).offset().top
}, 800, function(){
window.location.hash = hash;
});
}
});
});
//E-mail Validation Function
$(".test").hide();
function validateForm() {
const name = document.getElementById('name').value;
if (name == "") {
document.querySelector('.status').innerHTML = "Wypełnij wszystkie pola.";
return false;
}
const email = document.getElementById('email').value;
if (email == "") {
document.querySelector('.status').innerHTML = "Wpisz swój adres email";
return false;
} else {
const re = /^(([^<>()\[\]\\.,;:\s#"]+(\.[^<>()\[\]\\.,;:\s#"]+)*)|(".+"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
if (!re.test(email)) {
document.querySelector('.status').innerHTML = "Wpisz poprawny e-mail.";
return false;
}
}
const subject = document.getElementById('subject').value;
if (subject == "") {
document.querySelector('.status').innerHTML = "Wpisz temat wiadomości.";
return false;
}
const message = document.getElementById('message').value;
if (message == "") {
document.querySelector('.status').innerHTML = "Message cannot be empty";
return false;
}
document.querySelector('.status').innerHTML = "Wysyłanie...";
document.getElementById('contact-form').submit();
}

Maybe someone had similar problem, hope to see some tips from you guys. If you need another script just tell me hope we solve this together.
Best Regards Daniel.

you need to remove below css code form your css file.
.wrapper {
overflow-x: hidden;
}
and also need to update your font size for the element #kontakt p in media query of 576px right now it is 1.1rem you need to reduce it 0.9rem.
I hope after done this two minor changes your scrolling problem will be solved.

play and pause button is not working in carousel?

I am performing carousel play and pause using jquery and javascript in bootstrap. I have written the code but not getting where I missed.
Here is the full code which might let u catch my mistake.
The problem is that the buttons for play and pause are in the scope of carousel and the behaviour a button normally gives is not the same here.
For the current situation, the buttons are positioned below the prev button and performing the same action which prev is performing i.e. showing the previous image.

Proper Behaviour of Carousel play and pause.

yeah dude, i also had the problem while doing a course from coursera. It is not the problem with jquery. Set the "z-index" of "carouselButton" to 2 or higher and it should work

Yeah...set z-index: 1; to carouselButton ...it will definitely work.

After going through your script i discover you opt out an important detail in your code that is you didn't add pause: false after interval:2000. so your script code should have been presented this way.
<script>
$(document).ready(function(){
$("#mycarousel").carousel( { interval: 2000, pause: false } );
$("#carousel-pause").click(function(){
$("#mycarousel").carousel('pause');
});
$("#carousel-play").click(function(){
$("#mycarousel").carousel('cycle');
});
});
</script>
or you can make use of this
<script>
$('#mycarousel').carousel({
interval: 1500,
pause: false
});
$('#carousel-pause').click(function() {
$('#mycarousel').carousel('pause');
});
$('#carousel-play').click(function() {
$('#mycarousel').carousel('cycle');
});
</script>
either ways your code will be up and running fine when you click the pause or play button
