# Attachment: Stress

> Hostile names in a narrow column, a random state every 60 ms, and 200 items in one group. Nothing overflows and the layout holds.

Example: https://hextaui.com/docs/attachment/examples/stress
Component docs: https://hextaui.com/docs/attachment.md

## Add this example

```bash
npx shadcn@latest add https://hextaui.com/r/attachment-stress.json
```

This adds `components/examples/attachment/stress.tsx` with the Attachment component and the HextaUI theme tokens.
