Contribute to our next priorities

You can contribute to upcoming GC Design System work.

We’re actively seeking contributions for the following items:

Components

  • Tag / Badge: For categorizing and highlighting content, statuses, or metadata in a clear and consistent way.
  • Modal: For interruptive interactions that require user attention, such as confirmations or important actions.
  • Alert: For communicating system status, feedback, and important messages to users.
  • Tabs: For organizing related content into sections within the same view.
  • Subway / On this page: For helping users navigate longer pages or multi-step content with clear structure and orientation.
  • Autocomplete (Select): For improving usability when selecting from long or complex lists.

Styles

  • More icons: A consistent set of icons to support common actions and concepts across more GC services.
  • Colours: Continued evolution of the colour system to support accessibility, flexibility, and clarity in different contexts.

Templates and getting started

  • Page templates: Reusable page structures for common service patterns to help teams get started quickly.
  • Starter apps: Reference implementations that show how to use GCDS in real environments and reduce setup time.
  • Patterns: Common interaction patterns and layouts that help teams build consistent, usable services faster.

We’re also interested in user interactions that have a common application across GC services.

Submit your contributions to our next priorities directly in GitHub, with an account.

Provide any of the following for each component or pattern:

  • Examples of designs: screenshots, prototypes, links to live services.
  • Research findings: your discovery, use cases, or usability testing
  • Code: prototype or production code, or product implementations.
