## Frequently asked questions [#frequently-asked-questions]

<Accordions>
  <Accordion title="How do I dismiss the status row after download?">
    Completed (fetch mode) and failed attachments include a dismiss control that calls `download.reset()`. You can also call `reset()` yourself.
  </Accordion>

  <Accordion title="Can multiple list items share a single useDownload hook?">
    Yes. `useDownload` tracks `objectKey` internally so loading states and status toasts only affect the button matching the active key.
  </Accordion>

  <Accordion title="How do I show download progress instead of a spinner?">
    Use the [`ProgressDownloadButton`](https://dimah-s3.vercel.app/docs/react/ui/components/progress-download-button) component paired with `useDownload({ route, mode: "fetch" })`.
