Overview

A subnavigation provides a horizontal list of links for navigating related pages. Authors should slot <rh-navigation-link> elements as children; authors should avoid slotting bare <a> elements, which are deprecated. Each link must have visible text content for accessibility. When more than one subnav appears on a page, authors should set accessible-label so screen readers can distinguish them.

Overflow scroll buttons appear when links exceed the available space. All links are keyboard accessible via Tab and Enter.

import '@rhds/elements/rh-subnav/rh-subnav.js';
 
<rh-subnav>
  <a href="#">Users</a>
  <a href="#">Containers</a>
  <a href="#">Databases</a>
  <a href="#" aria-current="page">Servers</a>
  <a href="#">System</a>
  <a href="#">Network</a>
  <a href="#">Cloud</a>
</rh-subnav>

<link rel="stylesheet" href="../rh-subnav-lightdom.css">
 
import { Subnav } from "@rhds/elements/react/rh-subnav/rh-subnav.js";

// NOTE: React 19+ does not require these wrapper imports.
// You can use the custom elements directly as-is.

export const Demo = () => (
  <Subnav>
    <a href="#">Users</a>
    <a href="#">Containers</a>
    <a href="#">Databases</a>
    <a href="#" aria-current="page">Servers</a>
    <a href="#">System</a>
    <a href="#">Network</a>
    <a href="#">Cloud</a>
  </Subnav>
  <link rel="stylesheet" href="../rh-subnav-lightdom.css" />
);

Sets color palette, which affects the element's styles as well as descendants' color theme. Overrides parent color context. Your theme will influence these colors so check there first if you are seeing inconsistencies. See CSS Custom Properties for default values

Customize the default aria-label on the <nav> container. Defaults to "subnavigation" if no attribute/property is set.
