Tabs

@coinbase/cds-web@8.75.2

Tabs is a flexible, accessible tab list for switching between related views. Use `DefaultTab` and `DefaultTabsActiveIndicator` for a standard underline tab row without wiring custom components, or supply your own `TabComponent` and `TabsActiveIndicatorComponent` for full control. For pill-style selection, see SegmentedTabs.

import { Tabs, DefaultTabsActiveIndicator } from '@coinbase/cds-web/tabs'

Tabs manages which tab is active and positions the animated indicator. For pill / segmented controls, use SegmentedTabs instead.

Basics

Out of the box, Tabs uses DefaultTab for each row (headline text, optional DotCount via count / max on each tab) and DefaultTabsActiveIndicator for the animated underline. Set color / activeColor on Tabs for inactive / active label tokens, and activeBackground for the underline (forwarded to the indicator as its background token).

      gap={4}
      onChange={setActiveTab}
      tabs={tabs}
    />
  );
}

Dot counts

Optional count and max on each tab are forwarded to the badge next to the label (see DotCount).

Disabled

Disable the whole row with disabled, or set disabled: true on individual tab items.

      onChange={setActiveTab}
      tabs={tabs}
    />
  );
}

Accessibility

Provide a descriptive accessibilityLabel on Tabs for the tab list. DefaultTab sets aria-controls / aria-selected for each tab; pair tabs with role="tabpanel" regions in your page content when you switch panels.

Styling

Colors

You can set color and activeColor for label tokens, and activeBackground for the underline.

      onChange={setActiveTab}
      TabComponent={TabComponent}
      TabsActiveIndicatorComponent={ActiveIndicator}

}

Custom label content

Pass extra fields on each tab and read them in your TabComponent (for example icons).
