React Navigation Drawer (ナビゲーション ドロワー) の概要

React Navigation Drawer は、コンテンツ内で展開または縮小されることができるサイド ナビゲーションを提供します。ミニ バージョンが閉じている場合もナビゲーションへのクイック アクセスを提供します。そのコンテンツは完全にカスタマイズ可能であると同時に、デフォルトのメニュー項目のスタイルも提供します。

React Navigation Drawer の例

このサンプルは、IgrNavDrawer コンポーネントを作成する方法を示しています。

Navigation Drawer 項目の追加

IgrNavDrawer の使用を開始する最も簡単な方法は次のとおりです:

<IgrNavDrawer open={true}>
    <IgrNavDrawerHeaderItem>
        <span>Sample Drawer</span>
    </IgrNavDrawerHeaderItem>
    <IgrNavDrawerItem>
        <div slot="icon">
            <IgrIcon name="home" collection="material" />
        </div>
        <span slot="content">Home</span>
    </IgrNavDrawerItem>
    <IgrNavDrawerItem>
        <div slot="icon">
            <IgrIcon name="search" collection="material" />
        </div>
        <span slot="content">Search</span>

Navbar の統合

ドロワーには任意のコンテンツを提供できますが、IgrNavDrawerItem が定義済みのスタイル設定を項目に適用します。

コンポーネントを少し強化するために、IgrNavbar と組み合わせて使用できます。このようにして、より完成された外観を実現し、ドロワーの方法を使用できます。次の例でこれを見てみましょう:

<IgrNavbar>
    <div slot="start">
        <IgrIcon name="menu" collection="material"/>
    </div>
    <h2>Home</h2>
</IgrNavbar>

<IgrNavDrawer>
    <IgrNavDrawerHeaderItem>
        <span>Sample Drawer</span>
    </IgrNavDrawerHeaderItem>
    <IgrNavDrawerItem>
        <div slot="icon">
            <IgrIcon name="home" collection="material" />
        </div>
        <span slot="content">Home</span>
    </IgrNavDrawerItem>
    <IgrNavDrawerItem>
        <div slot="icon">
            <IgrIcon name="search" collection="material" />
        </div>
        <span slot="content">Search</span>
    </IgrNavDrawerItem>
</IgrNavDrawer>
tsx

また、すべての position の値を表示するためにいくつかのラジオ ボタンを追加しましょう。このように、1 つが選択されるたびに、ドロワーの位置を変更します。

<IgrRadioGroup alignment="horizontal">
    <IgrRadio value="start" labelPosition="after" checked={this.state.drawerPosition === "start"} onChange={this.onRadioChange}>
        <span>Start</span>
    </IgrRadio>
    <IgrRadio value="end" labelPosition="after" checked={this.state.drawerPosition === "end"} onChange={this.onRadioChange}>
        <span>End</span>
    </IgrRadio>
    <IgrRadio value="top" labelPosition="after" checked={this.state.drawerPosition === "top"} onChange={this.onRadioChange}>
        <span>Top</span>
    </IgrRadio>
    <IgrRadio value="bottom" labelPosition="after" checked={this.state.drawerPosition === "bottom"} onChange={this.onRadioChange}>
        <span>Bottom</span>
    </IgrRadio>
</IgrRadioGroup>

<IgrNavDrawer position={this.state.drawerPosition} />

public onRadioChange(e: IgrRadioChangeEventArgs) {
    if (e.checked == true) {
        this.setState({ drawerPosition: e.detail.value });
    }
}
tsx

そして最後に、Navigation Drawer を開閉する方法が必要です。これを実現するにはいくつかの方法がありますが、この例のために、次のことを行います:

public onMenuIconClick() {
    if (this.navDrawerRef) {
        this.navDrawerRef.show();
    }
}
tsx

すべてがうまくいけば、コンポーネントは次のようになります:

ミニ バリアント

ミニ バリアントを使用する場合、Navigation Drawer を閉じる代わりに幅を変更します。アイコンだけを残して、いつでも利用できるクイック ナビゲーションを維持するために使用されます。これを実現するには、ドロワーの mini スロットを設定するだけです。

<IgrNavDrawer>
    <IgrNavDrawerItem>
        <div slot="icon">
            <IgrIcon name="home" collection="material" />
        </div>
        <span slot="content">Home</span>
    </IgrNavDrawerItem>
    <IgrNavDrawerItem>
        <div slot="icon">
            <IgrIcon name="search" collection="material"/>
        </div>
        <span slot="content">Search</span>
    </IgrNavDrawerItem>
    <div slot="mini">
        <IgrNavDrawerItem>
            <div slot="icon">
                <IgrIcon name="home" collection="material"/>
            </div>
        </IgrNavDrawerItem>
        <IgrNavDrawerItem>
            <div slot="icon">
                <IgrIcon name="search" collection="material" />
            </div>
        </IgrNavDrawerItem>
    </div>
</IgrNavDrawer>

<IgrButton clicked={this.onButtonClick}>
    <span>Toggle</span>
</IgrButton>

スタイル設定

Navigation Drawer コンポーネントは、base、main、mini など、いくつかの CSS パーツも公開し、スタイルを完全に制御できるようにします。

igc-nav-drawer::part(base) {
  background: var(--ig-secondary-500);
}

igc-nav-drawer-item::part(base) {
  color: var(--ig-secondary-500-contrast);
}

igc-nav-drawer-item::part(base):hover {
  background-color: var(--ig-gray-800);
}

igc-nav-drawer-item[active]::part(base) {
