# Button: Smooth width

> The button eases to the width of each label instead of reserving space for the longest one, so nothing around it jumps.

Example: https://hextaui.com/docs/button/examples/smooth-width
Component docs: https://hextaui.com/docs/button.md

## Add this example

```bash
npx shadcn@latest add https://hextaui.com/r/button-smooth-width.json
```

This adds `components/examples/button/smooth-width.tsx` with the Button component and the HextaUI theme tokens.

## Source

```tsx title="components/examples/button/smooth-width.tsx"
"use client"

import { Button } from "@/components/ui/button"

function wait(ms: number) {
  return new Promise<void>((resolve) => setTimeout(resolve, ms))
}

export function ButtonSmoothWidth() {
  return (
    <Button
      feedback
      loadingLabel="Publishing to 3 regions…"
      successLabel="Live"
      onClick={() => wait(1600)}
    >
      Publish
    </Button>
  )
}
```
