Was macht die Komponente?

Die Navigations-Komponente zeigt eine Liste von Navigationslinks an, die Nutzenden helfen, durch die verschiedenen Bereiche einer Webseite oder Applikation zu navigieren. Diese wird als Overlay dargestellt und verbirgt sich hinter einem Hamburger-Menü.

Wann soll die Komponente eingesetzt werden?

• Um Nutzenden eine klare und zugängliche Möglichkeit zur Navigation durch die Webseite oder Applikation zu bieten.
• Wenn eine kompakte Navigation erforderlich ist.

Regeln

• Die Navigation soll hinter einem Hamburger-Icon versteckt sein und wird jeweils im Header als erstes Element platziert.
• Die Navigationslinks sollen logisch gruppiert und in einer sinnvollen Reihenfolge angeordnet sein.

Beispiele

The sbb-navigation component provides a way to present a navigation menu.

Some of its features are:

• uses a native dialog element;
• creates a backdrop for disabling interaction below the navigation;
• disables scrolling of the page content while open;
• manages focus properly by setting it on the first focusable element or the first action with the .sbb-active class;
• can act as a host for components as sbb-navigation-list,
  sbb-navigation-marker
  and sbb-navigation-section;

Interactions

To display the sbb-navigation component you can either provide a trigger element using the trigger property,
or call the open() method on the sbb-navigation component.

<!-- Trigger element -->
<sbb-button id="nav-trigger">Navigation trigger</sbb-button>

<!-- Navigation component with navigation sections -->
<sbb-navigation trigger="nav-trigger">
  <sbb-navigation-marker>
    <sbb-navigation-button aria-current="page" id="nav-section-1">Label 1</sbb-navigation-button>
    <sbb-navigation-button id="nav-section-2">Label 2</sbb-navigation-button>
    <sbb-navigation-link href="https://www.sbb.ch/some/route">Label 3</sbb-navigation-link>
  <sbb-navigation-marker>

  <sbb-navigation-marker>
    <sbb-navigation-button aria-pressed="true">Language 1</sbb-navigation-button>
    <sbb-navigation-button aria-pressed="false">Language 2</sbb-navigation-button>
    <sbb-navigation-button aria-pressed="false">Language 3</sbb-navigation-button>
  <sbb-navigation-marker>

  <sbb-navigation-section trigger="nav-section-1">
    <span slot="label">Title 1</span>
    <sbb-navigation-list>
      <span slot="label">Label 1.1</span>
      <sbb-navigation-link href="...">Label 1.1.1</sbb-navigation-link>
      <sbb-navigation-link href="...">Label 1.1.2</sbb-navigation-link>
      <sbb-navigation-link href="...">Label 1.1.3</sbb-navigation-link>
    </sbb-navigation-list>
    ...
    <sbb-button>Something</sbb-button>
  </sbb-navigation-section>
  ...
</sbb-navigation>

Accessibility

On opening, the focus will be automatically set on the first focusable element or the first action with the .sbb-active class and, if the action with this class has a connected section, the section will be opened and the focus will be set on the first focusable element or the first action with the .sbb-active class in the section.
When a navigation action is marked to indicate the user is currently on that page, aria-current="page" should be set on that action.
Similarly, if a navigation action is marked to indicate a selected option (e.g., the selected language) aria-pressed should be set on that action.
