## Import

```tsx
import { SegmentedTabs } from '@coinbase/cds-web/tabs/SegmentedTabs'
```

## Examples

SegmentedTabs is a controlled component that uses `activeTab` and `onChange` to manage selection state.

### Basics

#### Initial Value

You can set any tab as the initial active tab by passing it to the `activeTab` state.

```jsx live
function Example() {
  const tabs = [
    { id: 'buy', label: 'Buy' },
    { id: 'sell', label: 'Sell' },
    { id: 'convert', label: 'Convert' },
  ];
  const [activeTab, updateActiveTab] = useState(tabs[0]);
  const handleChange = useCallback((activeTab) => updateActiveTab(activeTab), []);
  return (
    <SegmentedTabs
      accessibilityLabel="Switch token action views"
      activeTab={activeTab}
      onChange={handleChange}
      tabs={tabs}
    />
  );
}
```

SegmentedTabs can also start with no active selection by passing `null`.

```jsx live
function Example() {
  const tabs = [
    { id: 'buy', label: 'Buy' },
    { id: 'sell', label: 'Sell' },
    { id: 'convert', label: 'Convert' },
  ];
  const [activeTab, updateActiveTab] = useState(null);
  const handleChange = useCallback((activeTab) => updateActiveTab(activeTab), []);
  return (
    <SegmentedTabs
      accessibilityLabel="Switch token action views"
      activeTab={activeTab}
      onChange={handleChange}
      tabs={tabs}
    />
  );
}
```

#### Disabled

The entire component can be disabled with the `disabled` prop.

```jsx live
function Example() {
  const tabs = [
    { id: 'buy', label: 'Buy' },
    { id: 'sell', label: 'Sell' },
    { id: 'convert', label: 'Convert' },
  ];
  const [activeTab, updateActiveTab] = useState(tabs[0]);
  const handleChange = useCallback((activeTab) => updateActiveTab(activeTab), []);
  return (
    <SegmentedTabs
      accessibilityLabel="Switch token action views"
      activeTab={activeTab}
      disabled
      onChange={handleChange}
      tabs={tabs}
    />
  );
}
```

Individual tabs can also be disabled while keeping others interactive.

```jsx live
function Example() {
  const tabs = [
    { id: 'buy', label: 'Buy' },
    { id: 'sell', label: 'Sell', disabled: true },
    { id: 'convert', label: 'Convert' },
  ];
  const [activeTab, updateActiveTab] = useState(tabs[0]);
  const handleChange = useCallback((activeTab) => updateActiveTab(activeTab), []);
  return (
    <SegmentedTabs
      accessibilityLabel="Switch token action views"
      activeTab={activeTab}
      onChange={handleChange}
      tabs={tabs}
    />
  );
}
```

### Styling

#### Border Radius

Set `borderRadius` to change the shape of both the container and the active indicator.

```jsx live
function Example() {
  const tabs = [
    { id: 'buy', label: 'Buy' },
    { id: 'sell', label: 'Sell' },
    { id: 'convert', label: 'Convert' },
  ];
  const [activeTab, updateActiveTab] = useState(tabs[0]);
  const handleChange = useCallback((activeTab) => updateActiveTab(activeTab), []);
  return (
    <SegmentedTabs
      accessibilityLabel="Switch token action views"
      activeTab={activeTab}
      borderRadius={300}
      onChange={handleChange}
      tabs={tabs}
    />
  );
}
```

Use the `styles` prop to set a different `borderRadius` on the active indicator than the outer container, with `padding` to create an inset effect.

```jsx live
function Example() {
  const tabs = [
    { id: 'buy', label: 'Buy' },
    { id: 'sell', label: 'Sell' },
    { id: 'convert', label: 'Convert' },
  ];
  const [activeTab, updateActiveTab] = useState(tabs[0]);
  const handleChange = useCallback((activeTab) => updateActiveTab(activeTab), []);
  return (
    <SegmentedTabs
      accessibilityLabel="Switch token action views"
      activeTab={activeTab}
      borderRadius={300}
      onChange={handleChange}
      padding={0.5}
      styles={{
        activeIndicator: { borderRadius: 'var(--borderRadius-200)' },
      }}
      tabs={tabs}
    />
  );
}
```

#### Labels

Labels can be customized with any `ReactNode`, including instances of `Icon`.

```jsx live
function Example() {
  const tabs = [
    { id: 'buy', label: <Icon name="chartLine" size="s" color="currentColor" active /> },
    { id: 'sell', label: <Icon name="chartCandles" size="s" color="currentColor" active /> },
    { id: 'convert', label: <Icon name="chartBar" size="s" color="currentColor" active /> },
  ];
  const [activeTab, updateActiveTab] = useState(tabs[0]);
  const handleChange = useCallback((activeTab) => updateActiveTab(activeTab), []);
  return (
    <SegmentedTabs
      accessibilityLabel="Switch token action views"
      activeTab={activeTab}
      borderRadius={300}
      gap={0.5}
      onChange={handleChange}
      padding={0.5}
      styles={{
        activeIndicator: { borderRadius: 'var(--borderRadius-200)' },
      }}
      tabs={tabs}
      width="fit-content"
    />
  );
}
```

### Custom Components

Use `TabComponent` and `TabsActiveIndicatorComponent` to fully customize the tabs and active indicator. Individual tabs can also be customized by providing a `Component` in the tab definition.

```jsx live
function Example() {
  const CustomActiveIndicator = useCallback(
    ({ activeTabRect }) => (
      <TabsActiveIndicator activeTabRect={activeTabRect} background="bgOverlay" />
    ),
    [],
  );

  const CustomTab = useCallback(({ id, label, disabled }) => {
    const { activeTab } = useTabsContext();
    const isActive = activeTab?.id === id;
    const renderedLabel = (
      <Text color={isActive ? 'fgPositive' : 'fgNegative'} font="label2" overflow="truncate">
        {label}
      </Text>
    );

    return (
      <SegmentedTab disabled={disabled} id={id} label={renderedLabel} style={{ borderRadius: 0 }} />
    );
  }, []);

  const tabs = [
    { id: 'buy', label: 'Buy' },
    { id: 'sell', label: 'Sell' },
    { id: 'convert', label: 'Convert' },
  ];
  const [activeTab, updateActiveTab] = useState(tabs[0]);
  const handleChange = useCallback((activeTab) => updateActiveTab(activeTab), []);
  return (
    <SegmentedTabs
      accessibilityLabel="Switch token action views"
      activeTab={activeTab}
      borderRadius={0}
      onChange={handleChange}
      tabs={tabs}
      TabComponent={CustomTab}
      TabsActiveIndicatorComponent={CustomActiveIndicator}
    />
  );
}
```

## Props
