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.

Presenting

There are two ways to use ion-modal: inline or via the modalController. Each method comes with different considerations, so be sure to use the approach that best fits your use case.

Inline Modals

ion-modal 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 modal. See Usage for an example of how to write a modal inline.

When using ion-modal with Angular, React, or Vue, the component you pass in will be destroyed when the modal is dismissed. As this functionality is provided by the JavaScript framework, using ion-modal without a JavaScript framework will not destroy the component you passed in. If this is a needed functionality, we recommend using the modalController instead.

Angular

Since the component you passed in needs to be created when the modal is presented and destroyed when the modal is dismissed, we are unable to project the content using <ng-content> internally. Instead, we use <ng-container> which expects an <ng-template> to be passed in. As a result, when passing in your component you will need to wrap it in an <ng-template>:

<ion-modal [isOpen]="isModalOpen">  <ng-template>    <app-modal-content></app-modal-content>  </ng-template></ion-modal>

When to use

Using a modal inline is useful when you do not want to explicitly wire up click events to open the modal. For example, you can use the is-open property to easily present or dismiss a modal based on some state in your application.

If you need fine grained control over when the modal is presented and dismissed, we recommend you use the modalController.

Controller Modals

ion-modal can also be presented programmatically by using the modalController imported from Ionic Framework. This allows you to have complete control over when a modal is presented above and beyond the customization that inline modals give you. See Usage for an example of how to use the modalController.

When to use

We typically recommend that you write your modals inline as it streamlines the amount of code in your application. You should only use the modalController for complex use cases where writing a modal inline is impractical.

Card Modal

Developers can create a card modal effect where the modal appears as a card stacked on top of your app's main content. To create a card modal, developers need to set the presentingElement property and the swipeToClose properties on ion-modal.

The presentingElement property accepts a reference to the element that should display under your modal. This is typically a reference to ion-router-outlet.

The swipeToClose property can be used to control whether or not the card modal can be swiped to close.

See Usage for examples on how to use the sheet modal.

Sheet Modal

Developers can create a sheet modal effect similar to the drawer components available in maps applications. To create a sheet modal, developers need to set the breakpoints and initialBreakpoint properties on ion-modal.

The breakpoints property accepts an array which states each breakpoint that the sheet can snap to when swiped. A breakpoints property of [0, 0.5, 1] would indicate that the sheet can be swiped to show 0% of the modal, 50% of the modal, and 100% of the modal. When the modal is swiped to 0%, the modal will be automatically dismissed.

The initialBreakpoint property is required so that the sheet modal knows which breakpoint to start at when presenting. The initalBreakpoint value must also exist in the breakpoints array. Given a breakpoints value of [0, 0.5, 1], an initialBreakpoint value of 0.5 would be valid as 0.5 is in the breakpoints array. An initialBreakpoint value of 0.25 would not be valid as 0.25 does not exist in the breakpoints array.

The backdropBreakpoint property can be used to customize the point at which the ion-backdrop will begin to fade in. This is useful when creating interfaces that have content underneath the sheet that should remain interactive. A common use case is a sheet modal that overlays a map where the map is interactive until the sheet is fully expanded.

See Usage for examples on how to use the sheet modal.

note

Note: The swipeToClose property has no effect when using a sheet modal as sheet modals must be swipeable in order to be usable.

Interfaces

Below you will find all of the options available to you when using the modalController. These options should be supplied when calling modalController.create().

interface ModalOptions {  component: any;  componentProps?: { [key: string]: any };  presentingElement?: HTMLElement;  showBackdrop?: boolean;  backdropDismiss?: boolean;  cssClass?: string | string[];  animated?: boolean;  swipeToClose?: boolean;
  mode?: 'ios' | 'md';  keyboardClose?: boolean;  id?: string;
  enterAnimation?: AnimationBuilder;  leaveAnimation?: AnimationBuilder;}

Dismissing

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.

Customization

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;}

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.

note

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);}

Interfaces

ModalOptions

interface ModalOptions<T extends ComponentRef = ComponentRef> {  component: T;  componentProps?: ComponentProps<T>;  presentingElement?: HTMLElement;  showBackdrop?: boolean;  backdropDismiss?: boolean;  cssClass?: string | string[];  animated?: boolean;  swipeToClose?: boolean;
  mode?: Mode;  keyboardClose?: boolean;  id?: string;  htmlAttributes?: ModalAttributes;
  enterAnimation?: AnimationBuilder;  leaveAnimation?: AnimationBuilder;
  breakpoints?: number[];  initialBreakpoint?: number;  backdropBreakpoint?: number;  handle?: boolean;}

ModalAttributes

interface ModalAttributes extends JSXBase.HTMLAttributes<HTMLElement> {}

Usage

Angular

import { Component } from '@angular/core';import { ModalController } from '@ionic/angular';import { ModalPage } from '../modal/modal.page';
@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 {}

Card 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();}

Sheet Modals

Controller

import { IonRouterOutlet } from '@ionic/angular';
constructor(private routerOutlet: IonRouterOutlet) {}
async presentModal() {  const modal = await this.modalController.create({    component: ModalPage,    initialBreakpoint: 0.5,    breakpoints: [0, 0.5, 1]  });  return await modal.present();}

Inline

<ion-modal [isOpen]="isModalOpen" [initialBreakpoint]="0.5" [breakpoints]="[0, 0.5, 1]">  <ng-template>    <modal-page></modal-page>  </ng-template></ion-modal>

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.

Javascript

customElements.define('modal-page', class extends HTMLElement {  connectedCallback() {    this.innerHTML = `<ion-header>  <ion-toolbar>    <ion-title>Modal Header</ion-title>    <ion-buttons slot="primary">      <ion-button onClick="dismissModal()">        <ion-icon slot="icon-only" name="close"></ion-icon>      </ion-button>    </ion-buttons>  </ion-toolbar></ion-header><ion-content class="ion-padding">  Modal Content</ion-content>`;  }});
function presentModal() {  // create the modal with the `modal-page` component  const modalElement = document.createElement('ion-modal');  modalElement.component = 'modal-page';  modalElement.cssClass = 'my-custom-class';
  // present the modal  document.body.appendChild(modalElement);  return modalElement.present();}

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:

const modalElement = document.createElement('ion-modal');modalElement.component = 'modal-page';modalElement.cssClass = 'my-custom-class';modalElement.componentProps = {  'firstName': 'Douglas',  'lastName': 'Adams',  'middleInitial': 'N'};

To get the data passed into the componentProps, query for the modal in the modal-page:

customElements.define('modal-page', class extends HTMLElement {  connectedCallback() {    const modalElement = document.querySelector('ion-modal');    console.log(modalElement.componentProps.firstName);
    ...  }}

Dismissing a Modal

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

async function dismissModal() {  await modal.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 modalElement.onWillDismiss();console.log(data);

Card 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.

const modalElement = document.createElement('ion-modal');modalElement.component = 'modal-page';modalElement.cssClass = 'my-custom-class';modalElement.swipeToClose = true;modalElement.presentingElement = document.querySelector('ion-nav');

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

const modalElement = document.createElement('ion-modal');modalElement.component = 'modal-page';modalElement.cssClass = 'my-custom-class';modalElement.swipeToClose = true;modalElement.presentingElement = await modalController.getTop(); // Get the top-most ion-modal

Sheet Modals

const modalElement = document.createElement('ion-modal');modalElement.component = 'modal-page';modalElement.initialBreakpoint = 0.5;modalElement.breakpoints = [0, 0.5, 1];

React

useIonModal requires being a descendant of <IonApp>. If you need to use a modal outside of an <IonApp>, consider using the component method instead.

/* Using with useIonModal Hook */ 
import React, { useState } from 'react';import { IonButton, IonContent, IonPage, useIonModal } from '@ionic/react';
const Body: React.FC<{  count: number;  onDismiss: () => void;  onIncrement: () => void;}> = ({ count, onDismiss, onIncrement }) => (  <div>    count: {count}    <IonButton expand="block" onClick={() => onIncrement()}>      Increment Count    </IonButton>    <IonButton expand="block" onClick={() => onDismiss()}>      Close    </IonButton>  </div>);
const ModalExample: React.FC = () => {  const [count, setCount] = useState(0);
  const handleIncrement = () => {    setCount(count + 1);  };
  const handleDismiss = () => {    dismiss();  };
  /**   * First parameter is the component to show, second is the props to pass   */  const [present, dismiss] = useIonModal(Body, {    count,    onDismiss: handleDismiss,    onIncrement: handleIncrement,  });
  return (    <IonPage>      <IonContent fullscreen>        <IonButton          expand="block"          onClick={() => {            present({              cssClass: 'my-class',            });          }}        >          Show Modal        </IonButton>        <div>Count: {count}</div>      </IonContent>    </IonPage>  );};

/* Using with IonModal Component */
import React, { useState } from 'react';import { IonModal, IonButton, IonContent } from '@ionic/react';
export const ModalExample: React.FC = () => {  const [showModal, setShowModal] = useState(false);
  return (    <IonContent>      <IonModal isOpen={showModal} cssClass='my-custom-class'>        <p>This is modal content</p>        <IonButton onClick={() => setShowModal(false)}>Close Modal</IonButton>      </IonModal>      <IonButton onClick={() => setShowModal(true)}>Show Modal</IonButton>    </IonContent>  );};

const App: React.FC = () => {  const routerRef = useRef<HTMLIonRouterOutletElement | null>(null);    return (    <IonApp>      <IonReactRouter>        <IonRouterOutlet ref={routerRef}>          <Route path="/home" render={() => <Home router={routerRef.current} />}  exact={true} />        </IonRouterOutlet>      </IonReactRouter>    </IonApp>  )};
...
interface HomePageProps {  router: HTMLIonRouterOutletElement | null;}
const Home: React.FC<HomePageProps> = ({ router }) => {  const [showModal, setShowModal] = useState(false);    return (    <IonPage>      <IonContent>        <IonModal          isOpen={showModal}          cssClass='my-custom-class'          swipeToClose={true}          presentingElement={router || undefined}          onDidDismiss={() => setShowModal(false)}>          <p>This is modal content</p>        </IonModal>      </IonContent>    </IonPage>  );};

In most scenarios, setting a ref on IonRouterOutlet and passing that ref's current value to 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 ref as the presentingElement.

<IonModal  ref={firstModalRef}  isOpen={showModal}  cssClass='my-custom-class'  swipeToClose={true}  presentingElement={router || undefined}  onDidDismiss={() => setShowModal(false)}>    <p>This is modal content</p>    <IonButton onClick={() => setShow2ndModal(true)}>Show 2nd Modal</IonButton>    <IonButton onClick={() => setShowModal(false)}>Close Modal</IonButton></IonModal><IonModal  isOpen={show2ndModal}  cssClass='my-custom-class'  presentingElement={firstModalRef.current}  swipeToClose={true}  onDidDismiss={() => setShow2ndModal(false)}>  <p>This is more modal content</p>  <IonButton onClick={() => setShow2ndModal(false)}>Close Modal</IonButton></IonModal>

Developers can also use this component directly in their template:

<template>  <ion-button @click="setOpen(true)">Show Modal</ion-button>  <ion-modal    :is-open="isOpenRef"    css-class="my-custom-class"    @didDismiss="setOpen(false)"  >    <Modal :data="data"></Modal>  </ion-modal></template>

export default defineComponent({  components: { IonModal, IonButton, Modal },  setup() {    const isOpenRef = ref(false);    const setOpen = (state: boolean) => isOpenRef.value = state;    const data = { content: 'New Content' };    return { isOpenRef, setOpen, data }  }});</script>

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

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.

<template>  <ion-page>    <ion-content>      <ion-button @click="setOpen(true)">Show Modal</ion-button>      <ion-modal        :is-open="isOpenRef"        css-class="my-custom-class"        :swipe-to-close="true"        :presenting-element="$parent.$refs.ionRouterOutlet"        @didDismiss="setOpen(false)"      >        <Modal :data="data"></Modal>      </ion-modal>    </ion-content>  </ion-page></template>
<script lang="ts">import { IonModal, IonButton, IonContent, IonPage } from '@ionic/vue';import { defineComponent, ref } from 'vue';import Modal from './modal.vue'
export default defineComponent({  components: { IonModal, IonButton, Modal, IonContent, IonPage },  setup() {    const isOpenRef = ref(false);    const setOpen = (state: boolean) => isOpenRef.value = state;    const data = { content: 'New Content' };    return { isOpenRef, setOpen, data }  }});</script>

export default {  components: { IonButton, IonContent, IonPage },  methods: {    async openModal() {      const modal = await modalController        .create({          component: Modal,          initialBreakpoint: 0.5,          breakpoints: [0, 0.5, 1]        })      return modal.present();    },  },}</script>
