Date Pickers provide an intuitive interface for users to select dates from a calendar or input field. They combine text input with a visual calendar component to offer multiple ways of date selection, improving both accessibility and user experience.
Guidance
| Aspect | Best Practice |
|---|---|
| Usage | Use Date Pickers for date selection tasks, scheduling, filtering, and form inputs where precise date selection is required. |
| Content | Provide clear labels, placeholder text, and validation messages to guide users through date selection. |
| Behavior | Support both keyboard input and mouse interaction, with proper validation and error handling for invalid dates. |
| Selection | Support single dates, date ranges, and multiple date selection modes based on the use case requirements. |
| Accessibility | Include proper ARIA labels, keyboard navigation support, and screen reader compatibility. |
| Formats | Use consistent date formatting that matches user expectations and locale conventions. |
