Edit on GitHub ↗

Prop types and inline documentation are included below. This is repository source; the installer rewrites shared imports for your project.

import { cn } from "../lib/cn";

  title: string;
  description?: string;
  time?: React.ReactNode;
}

export interface TimelineProps {
  entries: TimelineEntry[];
  className?: string;
}

/**
 * A vertical sequence of events, marked up as an ordered list — a screen
 * reader announces "item 2 of 5" for free, information a stack of styled
 * `<div>`s never carries. The connecting line uses `start-` positioning, so
 * it stays on the correct side of the text under RTL without a separate rule.
 */

  return (
    <ol className={cn("relative flex flex-col gap-6 ps-6", className)}>
