Thanks for your answer Arkadiusz, this feature would be nice to have for users who have to display a large amount of pictures!

I've found a solution by using ngx-gallery which provides nice and customisable carousels to fit my needs!

Unfortunately we don't have such feature in the current version of the carousel component. We will discuss this idea with our design team and consider implementing it in the future.

For now you can try to use custom styles to limit thumbnail list width and add horizontal scroll (add this styles to your global styles.scss file):

.carousel .carousel-thumbnails .carousel-indicators {
    width: 80%;
    margin-right: auto;
    margin-left: auto;
    overflow-x: scroll;
    justify-content: start;
}

.carousel .carousel-thumbnails .carousel-indicators li img {
    width: auto !important;
}
