The Ignite UI for Angular Toggle directive allows the users to wrap some content into a box which can be easily opened and closed.



First Steps

To get started with the Toggle directive, first you need to import the IgxToggleModule in your app.module.ts file:

// app.module.ts

import { IgxToggleModule } from 'igniteui-angular';

    imports: [..., IgxToggleModule]
export class AppModule {}

Display Toggle

In order to show and hide the toggle content, use its open and close methods:

import { IgxToggleDirective } from 'igniteui-angular'


export class Class {
    @ViewChild(IgxToggleDirective) toggle: IgxToggleDirective;

    toggleContent() {
        if (this.toggle.collapsed) {
        } else {

Then in the template of our component, we can apply the directive on the element we want to be togglable:

<button class="toggle-button" igxButton="raised" (click)="toggleContent()">Toggle</button>
<div class="toggle-content" igxToggle>
    <section class="toggle-section">
        <img src="assets/images/toggle/nature.jpg"/>


Change Position

In the next sample, we'll use a different positioning strategy so that the content is displayed below the button.

The igxToggle directive uses the IgxOverlayService provider. The open, close and toggle methods accept optional overlay settings that control how the content is displayed. If omitted, the default overlay settings are used as seen in the previous sample.


By defaut the closeOnOutsideClick property is set to true. In order to disable this functionallity, the property has to be set to false.

// template.component.ts

    @ViewChild(IgxToggleDirective) public igxToggle: IgxToggleDirective;
    @ViewChild("button") public igxButton: ElementRef;

    public _positionSettings = {
        horizontalStartPoint: HorizontalAlignment.Left,
        verticalStartPoint: VerticalAlignment.Bottom

    public _overlaySettings = {
        closeOnOutsideClick: false,
        positionStrategy: new ConnectedPositioningStrategy(this._positionSettings)

    public toggle() { = this.igxButton.nativeElement;

This is how our toggle should look like now:

Automatic Toggle Actions

In order to avoid using the open and close methods, we can use a directive, which has an onClick handler, and changes the state of the toggle we are referring to automatically.

If we would like to take advantage of this functionality, we will have to use the IgxToggleActionDirective from the IgxToggleModule and assign the IgxToggleDirective to it.


The IgxToggleActionDirective should be declared on the element we are planing to use like a trigger (toggle).

<button class="toggle-button"  igxButton="raised" [igxToggleAction]="toggleRef">Toggle</button>
<div class="toggle-content" igxToggle #toggleRef="toggle">
    <section class="toggle-section">
        <h6>Automatic toggle actions</h6>

After these changes the toggle should work exactly in the same way.


By default IgxToggleActionDirective excludes its host element from the closeOnOutsideClick property. Therefore, clicking on the host element will not fire any event. Additionally, this directive will set its host element as the position strategy target.

Automatic Toggle Service Provider

There is a convenient way to keep the state of the igxToggle directive and command it via the igxNavigationService provider. We just need to set an identifier for our igxToggle element, which will be used to register the toggle with the service. If we would like to control its state automatically, we have to pass this identifier to the igxToggleActionDirective.

<button igxToggleAction="toggleId" class="toggle-button" igxButton="raised">Toggle</button>
<div igxToggle id="toggleId" class="toggle-content">
    <section class="toggle-section">
        <h6>Toggled by the service provider</h6>

If all went well, it will look like this:

Offsetting the Toggle Container

We can manipulate the position of the toggle container along the corresponding axis by a provided amount:

// deltaX and deltaY determine by how much the container will be offset compared to its' previous position
public offsetToggle() {
    const deltaX = 30;
    const deltaY = 30;
    this.toggle.setOffset(deltaX, deltaY);
