Examples

Nested submenus

A NavigationMenu.Root component can be nested within a higher-level NavigationMenu.Content part to create a multi-level navigation menu.

Custom links

The NavigationMenu.Link part can be customized to render the link from your framework using the render prop to enable client-side routing.

Next.js example

import NextLink from 'next/link';
import { NavigationMenu } from '@base-ui-components/react/navigation-menu';

function Link(props: NavigationMenu.Link.Props) {
  return (
    <NavigationMenu.Link
      render={<NextLink href={props.href} />}
      {...props}
    />
  );
}

Large menus

When you have large menu content that doesn’t fit in the viewport in some cases, you usually have two choices:

Compress the navigation menu content

You can change the layout of the navigation menu to render less content or be more compact by reducing the space it takes up. If your content is flexible, you can use the max-height property on Popup to limit the height of the navigation menu to let it compress itself while preventing overflow.

Compact layout

.Content,
.Popup {
  max-height: var(--available-height);
}

Make the navigation menu scrollable

Scrollable layout

.Content,
.Popup {
  max-height: var(--available-height);
}

.Content {
  overflow-y: auto;
}

Native scrollbars will be visible while transitioning content, so we recommend using our Scroll Area component instead of native scrollbars to keep them hidden, which will also allow the Arrow to be centered correctly.
