I'll create an accessible form component with proper ARIA labels and error handling. This form will include input validation and display error messages for better user experience and accessibility.

This accessible form component includes the following accessibility features:

1. Proper labeling: Each form field has an associated label with a for attribute matching the input's id.
2. Error handling: Form validation errors are displayed with aria-live="polite" to ensure screen readers announce them when they appear.
3. Descriptive text: Each field has a description that provides additional context, linked to the input with aria-describedby.
4. Focus management: The form uses the shadcn/ui components, which handle focus states appropriately.
5. Keyboard navigation: All interactive elements are keyboard accessible.
6. Clear error messages: Validation errors are displayed clearly below each field.
7. Submit status: The form displays a success message after submission, with role="status" and aria-live="polite" to ensure screen readers announce it.
8. Disabled state: The submit button is disabled while the form is submitting to prevent multiple submissions.

This form is fully accessible and provides a great user experience for all users, including those using assistive technologies. The form validates input on the client-side using Zod and react-hook-form, providing immediate feedback to users about any input errors.

To use this form in your project, you'll need to ensure you have the necessary dependencies installed:

Also, make sure you have the shadcn/ui components installed and set up in your project.

Is there anything specific you'd like me to explain or modify in this accessible form component?
