ion-action-sheet

scoped

An Action Sheet is a dialog that displays a set of options. It appears on top of the app's content, and must be manually dismissed by the user before they can resume interaction with the app. Destructive options are made obvious in ios mode. There are multiple ways to dismiss the action sheet, including tapping the backdrop or hitting the escape key on desktop.

ion-action-sheet can be used by writing the component directly in your template. This reduces the number of handlers you need to wire up in order to present the Action Sheet.

Using isOpen

The isOpen property on ion-action-sheet allows developers to control the presentation state of the Action Sheet from their application state. This means when isOpen is set to true the Action Sheet will be presented, and when isOpen is set to false the Action Sheet will be dismissed.

isOpen uses a one-way data binding, meaning it will not automatically be set to false when the Action Sheet is dismissed. Developers should listen for the ionActionSheetDidDismiss or didDismiss event and set isOpen to false. The reason for this is it prevents the internals of ion-action-sheet from being tightly coupled with the state of the application. With a one way data binding, the Action Sheet only needs to concern itself with the boolean value that the reactive variable provides. With a two way data binding, the Action Sheet needs to concern itself with both the boolean value as well as the existence of the reactive variable itself. This can lead to non-deterministic behaviors and make applications harder to debug.

Controller Action Sheets

The actionSheetController can be used in situations where more control is needed over when the Action Sheet is presented and dismissed.

Buttons

A button's role property can either be destructive or cancel. Buttons without a role property will have the default look for the platform. Buttons with the cancel role will always load as the bottom button, no matter where they are in the array. All other buttons will be displayed in the order they have been added to the buttons array. Note: We recommend that destructive buttons are always the first button in the array, making them the top button. Additionally, if the action sheet is dismissed by tapping the backdrop, then it will fire the handler from the button with the cancel role.

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.

Collecting Role Information on Dismiss

When the didDismiss event is fired, the data and role fields of the event detail can be used to gather information about how the Action Sheet was dismissed.

Console
Console messages will appear here when logged from the example above.

Theming

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.

Styling

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.

/* 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;
}

CSS Custom Properties

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

Accessibility

Screen Readers

Action Sheets set aria properties in order to be accessible to screen readers, but these properties can be overridden if they aren't descriptive enough or don't align with how the action sheet is being used in an app.

Role

Action Sheets are given a role of dialog. In order to align with the ARIA spec, either the aria-label or aria-labelledby attribute must be set.

Action Sheet Description

It is strongly recommended that every Action Sheet have the header property defined, as Ionic will automatically set aria-labelledby to point to the header element. However, if you choose not to include a header, an alternative is to use the htmlAttributes property to provide a descriptive aria-label or set a custom aria-labelledby value.

const actionSheet = await this.actionSheetController.create({
htmlAttributes: {
'aria-label': 'action sheet dialog',
},
});

Action Sheet Buttons Description

Buttons containing text will be read by a screen reader. If a button contains only an icon, or a description other than the existing text is desired, a label should be assigned to the button by passing aria-label to the htmlAttributes property on the button.

const actionSheet = await this.actionSheetController.create({
header: 'Header',
buttons: [
{
icon: 'close',
htmlAttributes: {
'aria-label': 'close',
},
},
],
});
