How to carousel in loop?

I am trying to loop carousels with class “active” first item

here is my code

<div class="carousel-item active">
    <div class="top-top">
        <h4>some heading</h4>
        <iframe class="testimonial" width="100%" height="auto"
                src="https://www.youtube.com/embed/ynK2WIRg?rel=0" frameborder="0"
                allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="">
        </iframe>
    </div>
</div>

@foreach($test as $tes)
<div class="carousel-item">
    <div class="top-top">
        <h4>{{ $tes->name }}</h4>
        <iframe class="testimonial" width="100%" height="auto"
                src="https://www.youtube.com/embed/{{ $tes->file_name }}?rel=0" frameborder="0"
                allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="">
        </iframe>
    </div>
</div>
@endforeach
</div>

I trying to put active item in the loop too.

Answer

You can use $loop->iteration==1 as said in laravel blade doc inside the foreach:

@foreach($test as $tes)
    <div class="carousel-item @if($loop->iteration==1) active @endif">
        <div class="top-top">
        <h4>{{ $tes->name }}</h4>
        <iframe class="testimonial" width="100%" height="auto"
            src="https://www.youtube.com/embed/{{ $tes->file_name }}?rel=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="">
        </iframe>
        </div>
    </div>
@endforeach
