Horizontal Scroll Section

Playground

Tune the props live — the code snippet updates as you go, so you can dial in the look you want before copying it.

import * as React from "react";

export default function Example() {
  return (
    <div className="flex min-h-[320px] w-full items-center justify-center p-6">

<HorizontalScrollSection/>

    </div>
  );
}

Installation

Usage

The outer section automatically stretches out enough vertical scroll height for its content; as the user scrolls down, the inner track is pinned at the center of the screen and shifts to the left. Each direct child is one horizontal panel.

import { HorizontalScrollSection } from "@/components/ui/horizontal-scroll-section";

<HorizontalScrollSection gap={24} showProgress>
  {items.map((item) => (
    <div key={item.id} className="h-80 w-96 rounded-xl border p-6">
      {item.content}
    </div>
  ))}
</HorizontalScrollSection>;

If the section sits inside a nested overflow-y-auto container, pass that container's ref to container and the component will use it as the reference for pinning and scrolling:

const scrollerRef = React.useRef<HTMLDivElement>(null);

<div ref={scrollerRef} className="h-[80vh] overflow-y-auto">
  <HorizontalScrollSection container={scrollerRef}>
    {/* Panels */}
  </HorizontalScrollSection>
</div>;

Props

How it works

• Automatic measurement: a ResizeObserver measures the track's scrollWidth and the viewport width, derives the vertical scroll distance from "track width − viewport width", and stretches the outer section's height accordingly. It recalculates automatically whenever the content, the window, or the container changes size.
• Pinned displacement: the inner viewport is pinned with sticky top-0; useScroll reads the section's progress and useTransform maps it into a horizontal displacement x. With smooth on, that value additionally passes through useSpring for a soft, momentum-like settle.
• Correct on the first frame: measurement runs synchronously in a layout effect, so the very first frame already carries the correct height and the layout never jumps. All timers, ResizeObserver instances, and event listeners are fully cleaned up on unmount.
• Tuning: stiffness / damping control the feel and gap controls panel spacing; panel width and height are yours to set on the children (the example uses w-56 h-40).

Accessibility

• When the user has "reduce motion" enabled at the system level, it switches to native overflow-x-auto horizontal scrolling: the content stays fully accessible and no long stretch of vertical scroll is consumed.
• The scroll section carries role="region" and a customizable aria-label.
• When keyboard Tab moves focus to a panel that is currently outside the viewport, the component converts that into the matching vertical scroll position and smoothly brings the panel into view, so focus never disappears off screen.
