Timeline
Design System - Timeline component
The Timeline component visually represents a sequence of events or stages in a linear, chronological order. Designed with clarity and accessibility in mind, it helps users understand the progress, status, and associated actions within a workflow.
// Sample code
<CheckBox
label="Label"
onChange={(e)=>{console.log(e.target.checked}}
/>Anatomy
Variants
Upcoming
Displays future events or steps in the process. The visual indicator is muted to reflect inactivity, and it can include relevant date/time info.
In Progress
Represents tasks or stages currently underway. It uses an active visual indicator to denote ongoing status and may include interactive elements like “View Details”.
Completed
Marks finished tasks using a filled, completed icon. This variant reinforces a sense of progression and task completion.
Properties
Default
Shows only the stage name without additional data, keeping the interface clean.
Date
Includes the date beneath the stage to inform users of timing for events or steps.
Additional Elements
Enhances the component with date/time details and a collapsible “View Details” element, which opens further content.
Expanded
Displays rich content such as text blocks, image/document previews, and action buttons to support user interaction.
Error Timeline
Highlights failed or incomplete steps with red indicators and messaging like “Failed”, drawing attention to issues that require user attention.
Property Configuration Table
Each design component offers a range of configurable options. These options are intentionally platform-agnostic, allowing implementations to adapt and tailor them to align with the specific requirements of the chosen framework.

Behaviours
Progressive Expansion
Sections expand to reveal additional information, files, and actions only when the user chooses to explore, preventing visual clutter.
Usage Guide
Ensure Clear Status Representation
Each timeline status should be visually distinct using clear colours, icons, and typography so that users can easily understand the progression and current state.
Icons should clearly match their status. Avoid using similar icons for different statuses, which can lead to misinterpretation.
