Usage
usage.tsx
import FileUploadDemo from "@/registry/examples/file-upload-demo";export default function Example() { return <FileUploadDemo />;}- Use for forms that need a small multi-file attachment area.
- Use when users should be able to upload files by either dragging them into a dropzone or browsing from the filesystem.
- Use when the interface should visibly list selected files and allow individual removal.
- Use as a starting point for adding file validation feedback through toast notifications.
Examples
Standalone attachment section
Render the demo as the attachment area in a form or settings page.
standalone-attachment-section.tsx
import FileUploadDemo from "@/registry/examples/file-upload-demo";export default function AttachmentSection() { return ( <section aria-labelledby="attachments-heading"> <h2 id="attachments-heading">Attachments</h2> <FileUploadDemo /> </section> );}Dialog content
Use the complete upload experience inside a modal or dialog body.
dialog-content.tsx
import FileUploadDemo from "@/registry/examples/file-upload-demo";export default function UploadDialogContent() { return ( <div className="space-y-4"> <div> <h2 className="text-lg font-semibold">Upload documents</h2> <p className="text-sm text-muted-foreground">Add up to two files.</p> </div> <FileUploadDemo /> </div> );}Card-based upload area
Place the demo in a card alongside explanatory content.
card-based-upload-area.tsx
import FileUploadDemo from "@/registry/examples/file-upload-demo";export default function DocumentUploadCard() { return ( <div className="rounded-lg border p-6"> <div className="mb-4"> <h2 className="font-semibold">Supporting documents</h2> <p className="text-sm text-muted-foreground">PDF, image, or text files are supported.</p> </div> <FileUploadDemo /> </div> );}Accessibility
- The upload trigger is rendered as a button through FileUploadTrigger with asChild, so it can be activated by keyboard users.
- The dropzone and file-list accessibility behavior is provided by the underlying FileUpload components.
- The delete control is an icon-only button containing an X icon, but the source does not provide an aria-label; add an accessible name such as “Remove file” when adapting this example.
- The upload and delete icons do not define explicit accessible names and should remain decorative when the surrounding controls provide their names.
- Rejection feedback is announced visually through a Sonner toast; ensure the application’s toast provider is configured with an accessible live region.
