A Modal is a dialog that appears on top of the app's content, and must be dismissed by the app before interaction can resume. It is useful as a select component when there are a lot of options to choose from, or when filtering items in a list, as well as many other use cases.


The modal can be dismissed after creation by calling the dismiss() method on the modal controller. The onDidDismiss function can be called to perform an action after the modal is dismissed.


Modal 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 */.modal-wrapper {  background: #222;}
/* Works - pass "my-custom-class" in cssClass to increase specificity */.my-custom-class .modal-wrapper {  background: #222;}

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

.my-custom-class {  --background: #222;}

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.

ion-modal works under the assumption that stacked modals are the same size. As a result, each subsequent modal will have no box shadow and a backdrop opacity of 0. This is to avoid the effect of shadows and backdrops getting darker with each added modal. This can be changed by setting the --box-shadow and --backdrop-opacity CSS variables:

ion-modal.stack-modal {  --box-shadow: 0 28px 48px rgba(0, 0, 0, 0.4);  --backdrop-opacity: var(--ion-backdrop-opacity, 0.32);}


import { Component } from '@angular/core';import { ModalController } from '@ionic/angular';import { ModalPage } from '../modal/';
@Component({  selector: 'modal-example',  templateUrl: 'modal-example.html',  styleUrls: ['./modal-example.css'],})export class ModalExample {  constructor(public modalController: ModalController) {}
  async presentModal() {    const modal = await this.modalController.create({      component: ModalPage,      cssClass: 'my-custom-class',    });    return await modal.present();  }}
import { Component, Input } from '@angular/core';
@Component({  selector: 'modal-page',})export class ModalPage {  constructor() {}}

If you need a wrapper element inside of your modal component, we recommend using a <div class="ion-page"> so that the component dimensions are still computed properly.

Passing Data#

During creation of a modal, data can be passed in through the componentProps. The previous example can be written to include data:

async presentModal() {  const modal = await this.modalController.create({    component: ModalPage,    cssClass: 'my-custom-class',    componentProps: {      'firstName': 'Douglas',      'lastName': 'Adams',      'middleInitial': 'N'    }  });  return await modal.present();}

To get the data passed into the componentProps, set it as an @Input:

export class ModalPage {  // Data passed in by componentProps  @Input() firstName: string;  @Input() lastName: string;  @Input() middleInitial: string;}

Dismissing a Modal#

A modal can be dismissed by calling the dismiss method on the modal controller and optionally passing any data from the modal.

export class ModalPage {  ...
  dismiss() {    // using the injected ModalController this page    // can "dismiss" itself and optionally pass back data    this.modalController.dismiss({      'dismissed': true    });  }}

After being dismissed, the data can be read in through the onWillDismiss or onDidDismiss attached to the modal after creation:

const { data } = await modal.onWillDismiss();console.log(data);

Lazy Loading#

When lazy loading a modal, it's important to note that the modal will not be loaded when it is opened, but rather when the module that imports the modal's module is loaded.

For example, say there exists a CalendarComponent and an EventModal. The modal is presented by clicking a button in the CalendarComponent. In Angular, the EventModalModule would need to be included in the CalendarComponentModule since the modal is created in the CalendarComponent:

import { NgModule } from '@angular/core';import { CommonModule } from '@angular/common';import { IonicModule } from '@ionic/angular';
import { CalendarComponent } from './calendar.component';import { EventModalModule } from '../modals/event/event.module';
@NgModule({  declarations: [CalendarComponent],  imports: [IonicModule, CommonModule, EventModalModule],  exports: [CalendarComponent],})export class CalendarComponentModule {}

Swipeable Modals#

Modals in iOS mode have the ability to be presented in a card-style and swiped to close. The card-style presentation and swipe to close gesture are not mutually exclusive, meaning you can pick and choose which features you want to use. For example, you can have a card-style modal that cannot be swiped or a full sized modal that can be swiped.

Card style modals when running on iPhone-sized devices do not have backdrops. As a result, the --backdrop-opacity variable will not have any effect.

If you are creating an application that uses ion-tabs, it is recommended that you get the parent ion-router-outlet using this.routerOutlet.parentOutlet.nativeEl, otherwise the tabbar will not scale down when the modal opens.

import { IonRouterOutlet } from '@ionic/angular';
constructor(private routerOutlet: IonRouterOutlet) {}
async presentModal() {  const modal = await this.modalController.create({    component: ModalPage,    cssClass: 'my-custom-class',    swipeToClose: true,    presentingElement: this.routerOutlet.nativeEl  });  return await modal.present();}

In most scenarios, using the ion-router-outlet element as the presentingElement is fine. In cases where you are presenting a card-style modal from within another modal, you should pass in the top-most ion-modal element as the presentingElement.

import { ModalController } from '@ionic/angular';
constructor(private modalController: ModalController) {}
async presentModal() {  const modal = await this.modalController.create({    component: ModalPage,    cssClass: 'my-custom-class',    swipeToClose: true,    presentingElement: await this.modalController.getTop() // Get the top-most ion-modal  });  return await modal.present();}

Style Placement#

In Angular, the CSS of a specific page is scoped only to elements of that page. Even though the Modal can be presented from within a page, the ion-modal 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.
