<ComponentPreview name="button-default" peekCode wide />

## Usage

```tsx
import { Button } from '@/components/ui/button'
```

```tsx
<Button variant="outline">Button</Button>
```

## Link

You can use the `buttonVariants` helper to create a link that looks like a button.

```tsx
import { buttonVariants } from '@/components/ui/button'
```

```tsx
<Link className={buttonVariants({ variant: 'outline' })}>Click here</Link>
```

Alternatively, you can set the `asChild` parameter and nest the link component.

```tsx
<Button asChild>
  <Link href="/login">Login</Link>
</Button>
```

## Examples

### Sizes

Use the `size` prop to determine the size of the button.

<ComponentPreview name="button-sizes" />

### Variants

#### Default

Used when no `variant` is specified. Prefer this unless another variant fits better, as below.

<ComponentPreview name="button-default" />

#### Primary

Use sparingly for data insertion, confirming purchases, and other strong positive actions. Because it is so prominent, aim for at most one primary button in a viewport.

<ComponentPreview name="button-demo" />

#### Secondary

Can be used for signaling a data or config change, but not as serious as a primary button.
For destructive or side effect actions, use the `destructive` or `warning` variant.

<ComponentPreview name="button-secondary" />

#### Warning

Used for actions that might have a side effect, but not as serious as a destructive action.

<ComponentPreview name="button-warning" />

#### Destructive (currently `danger`)

Used for actions that will have a serious destructive side effect, like deleting data.

prop `variant` will probably be changed to `destructive` in the future.

<ComponentPreview name="button-destructive" />

#### Outline

Used for secondary actions, or actions that are not as important as the primary action.

<ComponentPreview name="button-outline" />

#### Ghost (currently `text`)

Used for actions that are not as important as the primary action, or for actions that are not as important as the primary action.

prop `variant` will probably be changed to `ghost` in the future.

<ComponentPreview name="button-ghost" />

#### Link

Used for actions that are not as important as the primary action, or for actions that are not as important as the primary action.

<ComponentPreview name="button-link" />

### Only an icon

Displaying only an Icon in a button.

<Admonition type="note" title="This feature requires more support" className="mt-3">
  We should update the button component to support this use case better.
</Admonition>

<ComponentPreview name="button-icon" />

### As child

Supports slot behavior with `asChild` prop.

<ComponentPreview name="button-as-child" />

### Split with dropdown

Pair a button with a chevron `DropdownMenu` trigger when there are variations of the same action, or alternative ways to accomplish the same goal. The default or most likely option should be used on the exposed button.

When secondary actions are related but distinct (not alternatives to the primary action) display the primary action as a button and place the rest in an overflow menu instead. See [Table multiple actions](./table#multiple-actions).

<ComponentPreview name="button-split-dropdown" peekCode />

Ensure the middle border is shared rather than doubled-up. Do not use `border-l-0` on the chevron button as that drops the divider on hover/focus. Instead:

- Primary action: `rounded-r-none` and `hover:z-10` so its border stacks above the chevron on hover.
- Chevron trigger: `rounded-l-none`, `shrink-0`, `px-[4px] py-[5px]`, and `-ml-px` to overlap the adjacent border by one pixel.
- Both: `focus-visible:z-10` so the focus ring stacks above the neighbour, and `focus-visible:rounded-r-sm` / `focus-visible:rounded-l-sm` so the squared-off edge is slightly rounded while the ring is shown.
- Chevron trigger only: `aria-label` describing the menu (the icon is decorative).

Inside [Admonition](../fragments/admonition#split-button-with-dropdown) actions when `layout="responsive"`: also use `flex w-full @lg:w-auto` with `flex-1 @lg:flex-none` on the primary action.

## Accessibility

[Keyboard focus](../accessibility#focus-management) is automatically handled:

- Enabled buttons default to `tabIndex={0}` (keyboard accessible)
- Buttons with native `disabled` default to `tabIndex={-1}` (removed from tab order)
- You can still override with an explicit `tabIndex` prop when needed
- Keyboard focus uses the shared `focus-ring` utility; variants do not change ring colour

You therefore don't need to manually set `tabIndex` for buttons using native `disabled`.

When a disabled action has a non-obvious reason and needs a tooltip, add `focusableWhenDisabled` so keyboard users can still focus the control. See [Disabled controls](../accessibility#disabled-controls).

### Focusable when disabled

Use `focusableWhenDisabled` with `disabled` when the action is blocked for a non-obvious reason and you need a tooltip or other explanation. The control stays in the tab order and uses `aria-disabled` instead of native `disabled`.

```tsx
<Button disabled focusableWhenDisabled>
  Pause project
</Button>
```

In Studio, `ButtonTooltip` adds `focusableWhenDisabled` to disabled buttons with tooltip text automatically.
