Hi. I wanted to add an image carousel but different setup from what’s available in the elements options. It would be a linear image carousel that is continuously rolling or scrolling. How can I do this?
This is the layout I’m trying to replicate
Hi @Marj_A ,
You could use the following custom code in a Custom HTML element to have a moving image carousel.
<div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.12.2/gsap.min.js">
</script>
<style>
.f-width {
max-width: unset !important;
}
.ms-wrapper{
overflow: hidden;
}
.imageContainer{
display: flex;
flex-direction: row;
gap: 25px;
width: 200%;
}
.imageContainer .image{
height: 103px;
width: 100%;
object-fit: scale-down;
}
</style>
<div class="ms-wrapper">

/*
This helper function makes a group of elements animate along the x-axis in a seamless, responsive loop.
Features:
- Uses xPercent so that even if the widths change (like if the window gets resized), it should still work in most cases.
- When each item animates to the left or right enough, it will loop back to the other side
- Optionally pass in a config object with values like "speed" (default: 1, which travels at roughly 100 pixels per second), paused (boolean), repeat, reversed, and paddingRight.
- The returned timeline will have the following methods added to it:
- next() - animates to the next element using a timeline.tweenTo() which it returns. You can pass in a vars object to control duration, easing, etc.
- previous() - animates to the previous element using a timeline.tweenTo() which it returns. You can pass in a vars object to control duration, easing, etc.
- toIndex() - pass in a zero-based index value of the element that it should animate to, and optionally pass in a vars object to control duration, easing, etc. Always goes in the shortest direction
- current() - returns the current index (if an animation is in-progress, it reflects the final index)
- times - an Array of the times on the timeline where each element hits the "starting" spot. There's also a label added accordingly, so "label1" is when the 2nd element reaches the start.
