scoped

Contents

Action Sheetは複数の選択肢を表示するダイアログです。アプリのコンテンツ上に表示され、ユーザが手動で破棄しないとアプリの利用を再開することはできません。ios modeでは、破壊的な選択肢は明示されます(コンテンツの削除などは赤字などでわかりやすく表示されます)。Action Sheetを破棄するには、背景をタップする、デスクトップのパソコンの場合はエスケープキーを押すなど、複数の選択肢があります。

Button

Buttonの role プロパティは、 destructivecancel のどちらかを利用できます。 roleプロパティがない場合は、プラットフォームに応じたデフォルトの外観となります。cancel role を持つButtonは、配列 buttons のどこに配置してもAction Sheetの最下部に表示されます。 Note: destructive roleをつけるButtonは、一番上のButtonとして配置することをおすすめします。また、背景をタップしてAction Sheetを破棄した場合、cancel role に設定されているhandlerが実行されます。

A button can also be passed data via the data property on ActionSheetButton. This will populate the data field in the return value of the onDidDismiss method.

Customization

Action Sheet uses scoped encapsulation, which means it will automatically scope its CSS by appending each of the styles with an additional class at runtime. Overriding scoped selectors in CSS requires a higher specificity selector.

We recommend passing a custom class to cssClass in the create method and using that to add custom styles to the host and inner elements. This property can also accept multiple classes separated by spaces. View the Usage section for an example of how to pass a class using cssClass.

/* DOES NOT WORK - not specific enough */
.action-sheet-group {
background: #e5e5e5;
}

/* Works - pass "my-custom-class" in cssClass to increase specificity */
.my-custom-class .action-sheet-group {
background: #e5e5e5;
}

Any of the defined CSS Custom Properties can be used to style the Action Sheet without needing to target individual elements:

.my-custom-class {
--background: #e5e5e5;
}
note

If you are building an Ionic Angular app, the styles need to be added to a global stylesheet file. Read Style Placement in the Angular section below for more information.

}

Style Placement

In Angular, the CSS of a specific page is scoped only to elements of that page. Even though the Action Sheet can be presented from within a page, the ion-action-sheet element is appended outside of the current page. This means that any custom styles need to go in a global stylesheet file. In an Ionic Angular starter this can be the src/global.scss file or you can register a new global style file by adding to the styles build option in angular.json.
