Shadcn Timeline

What is Shadcn Timeline?

ReUI Timeline is a composable list-based component that renders event nodes connected by a vertical or horizontal line. Each node has an icon, avatar, or status indicator on the line, and a content panel beside it containing timestamp, title, description, metadata, and optional actions. The component does not prescribe a data format: pass any array of events and render each node with the content you need.

Twelve components show the Timeline in realistic production contexts: a deployment log where each deploy event is collapsible to reveal raw log output; an activity feed where commits, comments, and deployments share the same timeline with user Avatar nodes; a horizontal milestone tracker for release or project progress; and a pipeline step indicator for CI/CD status.

Why Use Shadcn Timeline?

Timelines are essential in DevOps dashboards (deployment history, CI/CD pipeline steps), project management tools (milestone progress, sprint activity), e-commerce (order status), and SaaS audit logs (user activity, billing history). A consistent, accessible timeline component prevents ad-hoc list implementations that vary in spacing, icon size, and line rendering across the product.

Collapsible log entries let users expand individual timeline events for detail without navigating away: critical for deployment logs where the event title is a summary and the full output is hundreds of lines. Pair with Shadcn Collapsible for expandable nodes and Shadcn Frame for timeline panels in dashboards.

Shadcn Timeline Features

• Vertical and Horizontal Orientation. Switch between vertical (events stacked top to bottom) and horizontal (events left to right) layout. Horizontal orientation works well for milestone trackers and pipeline step indicators.
• Deployment Log with Collapsible Entries. Timeline nodes wrap shadcn Collapsible so users can expand a deployment event to read the full build log inline without page navigation. Spinner shows active deployment state.
• Activity Feed with Avatars. Activity feed component renders user Avatar nodes on the timeline line for commits, comments, reviews, and deploys: the standard GitHub-style activity feed component.
• Roadmap and Milestone Variants. Roadmap timeline groups milestones by quarter or status with Badge labels. Milestone list shows completion state with icon changes from pending to completed.
• Order Status and Pipeline Steps. Order status component tracks shipment stages with color-coded state icons. Pipeline steps show CI/CD stage progression: build, test, deploy: with per-step status.
• Git Activity History. Git activity component renders commits, merges, and branches in timeline order with commit hash, message, and author avatar: adaptable to any version control activity feed.
• Leading and Trailing Labels. Horizontal timeline variant supports leading labels (above or below the line) for date and milestone labels, keeping the timeline line clean while surfacing temporal context.
• Frame Container Integration. Timeline components inside Frame containers include a toolbar, header, and optional action button. Renders as a self-contained dashboard widget for activity sidebars and DevOps panels.

ReUI Timeline: In-House Custom Shadcn Component

ReUI Timeline is an in-house component built and maintained by the ReUI team as part of the ReUI open-source library. It is designed to integrate seamlessly into any shadcn/ui project: following the same copy-and-own installation model. The component source lands directly in your repository; you own it, extend it, and style it with your Tailwind CSS tokens. ReUI Timeline is a custom chronological event component not available in base shadcn/ui. It composes Avatar, Badge, Collapsible, Frame, and Spinner to render deployment logs, activity feeds, order status, git history, roadmaps, and pipeline step indicators. Twelve components cover vertical, horizontal, and leading-label layouts with Collapsible-wrapped log entries for expandable detail.

The component is available in two API flavors to match your primitive stack: a Radix UI version for teams using Radix-based shadcn primitives, and a Base UI version for teams on @base-ui/react. Both versions share identical visual output and Tailwind CSS styling: only the underlying headless primitive differs. ReUI maintains 10+ such in-house components, all available in both Radix and Base UI versions, each with dedicated documentation covering the full component API, usage examples, and prop references.
