## Best for

A preselected PDF choice among 5, a button labeled with the picked extension, and a status line naming the result

- The Export `Button` only stores the pick in `exported` for the status line; run your export there

npx shadcn@latest add @reui/c-file-type-12

## About Shadcn File Type

### When to use

- Attachment lists, upload queues and file browser rows, each icon resolved from a name or MIME type
- Export format pickers and legends of the formats a product accepts or produces
- Version tags, document codes and marks such as a lock or star drawn on a document

### When not to use

- A drop zone or picker that collects documents before they are sent: use [File Upload](https://reui.io/components/file-upload.md) (`get_component("file-upload")`)
- Documents carried by a chat message as chips with idle, uploading and error states: use [Attachment](https://reui.io/components/attachment.md) (`get_component("attachment")`)
- A complete drive page with a folder tree, list and grid views and bulk actions: use the [Files blocks](https://reui.io/blocks/solutions/files.md)

### Agent notes

- `type` takes an extension, not a file name: report.pdf passed straight in draws a neutral page labeled REPORT.PDF, so run names through `getFileType`
- `FileType` is not focusable and has no keyboard behavior, so an action goes on a wrapping `Button` or link with its own accessible name

Every ReUI item has a twin like this one; the index is https://reui.io/llms.txt. Agents with the ReUI MCP (https://reui.io/docs/mcp) get the same guidance from the getters named above.
