使い方
タブは、ユーザーが異なるビューやカテゴリーを切り替える際に、関連するコンテンツを個別のセクションに整理するのに適しています。
タブを使用する場合:
- 関連するコンテンツを個別のセクションに整理する
- 複数のカテゴリーを持つ設定パネルを作成する
- 複数のトピックを持つドキュメントを構築する
- 異なるビューを持つダッシュボードを実装する
- ユーザーがコンテキストを切り替える必要があるコンテンツを表示する
タブを避ける場合:
- シーケンシャルなフォームやウィザードを構築する(ステッパーパターンを使用)
- ページ間をナビゲートする(ルーターナビゲーションを使用)
- 単一のコンテンツセクションを表示する(タブは不要)
- 7〜8個以上のタブがある(異なるレイアウトを検討)
機能
- 選択モード - フォーカス時にタブを自動的にアクティブにするか、手動でのアクティベーションを要求します
- キーボードナビゲーション - 矢印キー、Home、Endキーによる効率的なタブナビゲーション
- 向き - 水平または垂直のタブリストレイアウト
- 遅延コンテンツ - タブパネルは最初にアクティブになったときにのみレンダリングされます
- 無効化されたタブ - フォーカス管理機能付きで個々のタブを無効化します
- フォーカスモード - roving tabindexまたはactivedescendantによるフォーカス戦略
- RTLサポート - 右から左へ記述する言語のナビゲーション
例
フォーカスに追従する選択
フォーカスに追従する選択では、矢印キーで移動するとタブがすぐにアクティブになります。これにより、即座にフィードバックが得られ、軽量なコンテンツに適しています。

この動作を有効にするには、タブリストに [selectionMode]="'follow'" を設定します。
手動でのアクティブ化
手動でのアクティブ化では、矢印キーは選択されたタブを変更せずにタブ間でフォーカスを移動します。ユーザーはSpaceキーまたはEnterキーを押して、フォーカスされたタブをアクティブにします。

重いコンテンツパネルで不要なレンダリングを避けるには、[selectionMode]="'explicit'" を使用します。
垂直タブ
設定パネルやナビゲーションサイドバーのようなインターフェースでは、タブを垂直に配置します。

タブリストに [orientation]="'vertical'" を設定します。ナビゲーションは上/下矢印キーに変わります。
コンテンツの遅延レンダリング
ng-template で ngTabContent ディレクティブを使用すると、タブパネルが最初に表示されるまでレンダリングを遅延させることができます。
<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>
<!-- このコンテンツは、タブ1が最初に表示されたときにのみレンダリングされます -->
<app-heavy-component />
</ng-template>
</div>
<div ngTabPanel value="tab2">
<ng-template ngTabContent>
<!-- このコンテンツは、タブ2が最初に表示されたときにのみレンダリングされます -->
<app-another-component />
</ng-template>
</div>
</div>
デフォルトでは、パネルが非表示になった後もコンテンツはDOMに残ります。パネルが非アクティブ化されたときにコンテンツを削除するには、[preserveContent]="false" を設定します。
無効化されたタブ
特定のタブを無効にして、ユーザーの操作を防ぎます。無効化されたタブがキーボードフォーカスを受け取れるかどうかを制御します。

タブリストで [softDisabled]="true" の場合、無効化されたタブはフォーカスを受け取れますが、アクティブにはできません。[softDisabled]="false" の場合、無効化されたタブはキーボードナビゲーション中にスキップされます。
API
Tabs
タブリストとパネルを調整するコンテナディレクティブです。
このディレクティブには入力と出力がありません。ngTabList、ngTab、ngTabPanelディレクティブのルートコンテナとして機能します。
TabList
選択とキーボードナビゲーションを管理するタブボタンのコンテナです。
Inputs
| プロパティ | 型 | デフォルト | 説明 |
|---|---|---|---|
orientation |
'horizontal' | 'vertical' |
'horizontal' |
タブリストのレイアウト方向 |
wrap |
boolean |
false |
キーボードナビゲーションが最後のタブから最初のタブにラップするかどうか |
softDisabled |
boolean |
true |
trueの場合、無効化されたタブはフォーカス可能ですが、アクティブにはできません |
selectionMode |
'follow' | 'explicit' |
'follow' |
タブがフォーカス時にアクティブになるか、明示的なアクティベーションが必要か |
selectedTab |
any |
— | 現在選択されているタブの値(双方向バインディングをサポート) |
Tab
個々のタブボタンです。
Inputs
| プロパティ | 型 | デフォルト | 説明 |
|---|---|---|---|
value |
any |
— | 必須。 このタブの一意な値 |
disabled |
boolean |
false |
このタブを無効化します |
シグナル
| プロパティ | 型 | 説明 |
|---|---|---|
selected |
Signal<boolean> |
タブが現在選択されているかどうか |
active |
Signal<boolean> |
タブが現在フォーカスを持っているかどうか |
TabPanel
タブに関連付けられたコンテンツパネルです。
Inputs
| プロパティ | 型 | デフォルト | 説明 |
|---|---|---|---|
value |
any |
— | 必須。 関連付けられたタブのvalueと一致する必要があります |
preserveContent |
boolean |
true |
非アクティブ化後もパネルコンテンツをDOMに保持するかどうか |
シグナル
| プロパティ | 型 | 説明 |
|---|---|---|
visible |
Signal<boolean> |
パネルが現在表示されているかどうか |
TabContent
タブパネルのコンテンツを遅延レンダリングするための構造ディレクティブです。
このディレクティブには入力、出力、メソッドはありません。タブパネル内のng-template要素に適用します:
<div ngTabPanel value="tab1">
<ng-template ngTabContent>
<!-- ここのコンテンツは遅延レンダリングされます -->
</ng-template>
</div>
