By default, the Scrollable list uses the slide effect when switching slides.
To use the fade effect, please add this code to Custom CSS field in Content Views >> Settings page:
/* Scrollable list – fade effect */
.pt-cv-carousel .item{transition:opacity ease-in-out .5s!important}.pt-cv-carousel .active.left,.pt-cv-carousel .active.right,.pt-cv-carousel .item{opacity:0!important}.pt-cv-carousel .active,.pt-cv-carousel .next.left,.pt-cv-carousel .prev.right{opacity:1!important}.pt-cv-carousel .active.left,.pt-cv-carousel .active.right,.pt-cv-carousel .next,.pt-cv-carousel .prev{transform:translate3d(0,0,0)!important}
Best regards,
