  • Difference #1
• Fluent UI React V9 Storybook for implementation differences and document
  • Difference #1
• Open GitHub issues related to component
  • [link to each issue]
• (Optional) Draft implementation
  • [link to draft implementation, if applicable]
• Component Spec authored and reviewed

Implementation

• Initial conformance and unit tests (validate basic functionality)
• Initial documentation
  • Storybook stories
  • README.md covering basic usage
• Uses design tokens for styling
• Renders correctly in High Contrast mode

Validation

• Add tests
  • Unit and conformance tests
  • Bundle size fixtures
  • Performance test scenario
  • Accessibility behavior tests
