ion-backdrop

Backdrops are full screen components that overlay other components. They are useful behind components that transition in on top of other content and can be used to dismiss that component.

Usage

Angular

<!-- Default backdrop -->
<ion-backdrop></ion-backdrop>

<!-- Backdrop that is not tappable -->
<ion-backdrop tappable="false"></ion-backdrop>

<!-- Backdrop that is not visible -->
<ion-backdrop visible="false"></ion-backdrop>

<!-- Backdrop with propagation -->
<ion-backdrop stopPropagation="false"></ion-backdrop>

<!-- Backdrop that sets dynamic properties -->
<ion-backdrop
  [tappable]="enableBackdropDismiss"
  [visible]="showBackdrop"
  [stopPropagation]="shouldPropagate">
</ion-backdrop>

import { Component } from '@angular/core';

@Component({
  selector: 'backdrop-example',
  templateUrl: 'backdrop-example.html',
  styleUrls: ['./backdrop-example.css'],
})
export class BackdropExample {
