Buttons are used primarily for actions, such as “Add”, “Close”, “Cancel”, or “Save”.


```ts?title: "JavaScript"

import {extend, Button} from '@shopify/admin-ui-extensions';

extend('Playground', (root) => {
  const button = root.createComponent(Button, {
    title: 'Settings',
    kind: 'primary',
    appearance: 'critical',
    size: 'large',
    inlineSize: 'fill',
    accessibilityLabel: 'open settings',
    disabled: false,
    onPress: () => console.log('Pressed'),
  });

  root.appendChild(button);
  root.mount();
});


```

```jsx?title: "React"

import React from 'react';
import {extend, render, Button} from '@shopify/admin-ui-extensions-react';

function App() {
  return (
    <Button
      title="Settings"
      kind="primary"
      appearance="critical"
      size="large"
      inlineSize="fill"
      accessibilityLabel="open settings"
      disabled={false}
      onPress={() => console.log('Pressed')}
    />
  );
}

extend(
  'Playground',
  render(() => <App />),
);


```





## Guidelines

- Buttons will wrap their content if placed inside a `Stack` component, otherwise they will expand to the width of the container
- Buttons wrap their content, regardless of the container they are placed in

| ✅ Do                                              | 🛑 Don't                                     |
| -------------------------------------------------- | -------------------------------------------- |
| Align buttons vertically                        | Buttons should not be stacked horizontally |
| Use short, succinct titles that describe an action |                                              |
| Use an icon to supplement the title of the button  |                                              |
| Use only a single primary Button per section       |                                              |
| Primary buttons should be before secondary buttons |                                              |  |
