Vue d'ensemble
Les tabs (onglets) affichent des sections de contenu superposées dont un seul panneau est visible à la fois. Les utilisateurs passent d'un panneau à l'autre en cliquant sur les boutons d'onglet ou en parcourant la liste d'onglets avec les touches fléchées.

Utilisation
Les tabs conviennent bien pour organiser du contenu lié en sections distinctes, lorsque les utilisateurs passent d'une vue ou d'une catégorie à l'autre.
Utilisez des tabs lorsque vous :
- Organisez du contenu lié en sections distinctes
- Créez des panneaux de paramètres comportant plusieurs catégories
- Construisez une documentation couvrant plusieurs sujets
- Implémentez des tableaux de bord avec différentes vues
- Affichez du contenu entre lequel les utilisateurs doivent changer de contexte
Évitez les tabs lorsque vous :
- Construisez des formulaires séquentiels ou des assistants (utilisez un pattern stepper)
- Naviguez entre des pages (utilisez la navigation du router)
- Affichez une seule section de contenu (les tabs sont inutiles)
- Avez plus de 7 à 8 onglets (envisagez une autre mise en page)
Fonctionnalités
- Modes de sélection - Les onglets s'activent automatiquement au focus ou nécessitent une activation manuelle
- Navigation au clavier - Touches fléchées, Début et Fin pour naviguer efficacement entre les onglets
- Orientation - Disposition horizontale ou verticale de la liste d'onglets
- Contenu lazy - Les panneaux d'onglet ne sont rendus qu'une fois activés
- Onglets désactivés - Désactivez des onglets individuels avec gestion du focus
- Modes de focus - Stratégies de focus roving tabindex ou activedescendant
- Prise en charge RTL - Navigation pour les langues de droite à gauche
Exemples
La sélection suit le focus
Lorsque la sélection suit le focus, les onglets s'activent immédiatement à mesure que vous naviguez avec les touches fléchées. Cela fournit un retour instantané et convient bien aux contenus légers.

Définissez [orientation]="'vertical'" sur la liste d'onglets. La navigation passe alors aux touches fléchées Haut/Bas.
Rendu lazy du contenu
Utilisez la directive ngTabContent sur un ng-template pour différer le rendu des panneaux d'onglet jusqu'à ce qu'ils soient affichés.
<div ngTabs>
<ul ngTabList [(selectedTab)]="selectedTab">
<li ngTab value="tab1">Tab 1</li>
<li ngTab value="tab2">Tab 2</li>
</ul>
<div ngTabPanel value="tab1">
<ng-template ngTabContent>
<!-- This content only renders when Tab 1 is shown -->
<app-heavy-component />
</ng-template>
</div>
<div ngTabPanel value="tab2">
<ng-template ngTabContent>
<!-- This content only renders when Tab 2 is shown -->
<app-another-component />
</ng-template>
</div>
</div>
Par défaut, le contenu est retiré du DOM lorsque le panneau est masqué. Définissez [preserveContent]="true" pour le conserver, par exemple lorsque le panneau contient une vidéo qui ne doit pas être réinitialisée lors du changement d'onglet.
Onglets désactivés
Désactivez certains onglets pour empêcher toute interaction de l'utilisateur. Vous contrôlez si les onglets désactivés peuvent recevoir le focus clavier.

Tests
Angular Aria fournit des harnais de composant pour tester les composants de tabs. Voici un exemple d'utilisation des harnais dans un test de composant :
import {ComponentFixture, TestBed} from '@angular/core/testing';
import {TestbedHarnessEnvironment} from '@angular/cdk/testing/testbed';
import {ComponentHarness, HarnessLoader} from '@angular/cdk/testing';
import {TabsHarness} from '@angular/aria/tabs/testing';
import {MyTabsComponent} from './my-tabs'; // Your component
// A simple harness to help query content inside the tab panel
class TestContentHarness extends ComponentHarness {
static hostSelector = '.test-content';
async getText(): Promise<string> {
return (await this.host()).text();
}
}
describe('MyTabsComponent', () => {
let fixture: ComponentFixture<MyTabsComponent>;
let loader: HarnessLoader;
beforeEach(async () => {
TestBed.configureTestingModule({
imports: [MyTabsComponent],
});
fixture = TestBed.createComponent(MyTabsComponent);
await fixture.whenStable();
loader = TestbedHarnessEnvironment.loader(fixture);
});
it('should switch tabs and scope panel queries', async () => {
const tabs = await loader.getHarness(TabsHarness);
// Get all tabs
const tabItems = await tabs.getTabs();
expect(tabItems.length).toBe(3);
// Verify initial selection
expect(await tabItems[0].isSelected()).toBe(true);
expect(await tabItems[1].isSelected()).toBe(false);
// Query content inside the active tab panel
// TabHarness automatically scopes queries to its associated panel
const content = await tabItems[0].getHarness(TestContentHarness);
expect(await content.getText()).toBe('Content 1');
// Switch to the second tab
await tabItems[1].select();
// Verify selection updated
expect(await tabItems[0].isSelected()).toBe(false);
expect(await tabItems[1].isSelected()).toBe(true);
});
});
