Angular Material Dialog Position : Right, Left, Top, Bottom

By Arvind Rai, November 11, 2022
On this page we will learn to set Material Dialog position in right, left, top, bottom or anywhere in the display area in our Angular Material application.
1. Material dialog is opened using method. The parameters are ComponentType/TemplateRef and MatDialogConfig.
2. The MatDialogConfig has a position property to set the position of the dialog. The position property takes the instance of DialogPosition.
3. The properties of DialogPosition are right, left, top and bottom whose values can be set in px, em, % etc.
4. The default position of dialog is in center.

1. Technologies Used

Find the technologies being used in our example.
1. Angular 13.1.0
2. Angular Material 13.3.9
3. Node.js 12.20.0
4. NPM 8.2.0


The method opens a modal dialog containing the given component. 
Parameters :
component: ComponentType<T> : Type of the component to load into the dialog.
config?: MatDialogConfig<D> : Extra configuration options.
Returns :
MatDialogRef<T, R>

3. MatDialogConfig

The MatDialogConfig is the configuration for opening a modal dialog. Find some of its properties.
data : Data being injected into the child component.
height : Height of the dialog.
width : Width of the dialog.
position : Position of the dialog. It accepts DialogPosition.

4. Position

By default, dialog position is in center. We can change it by using position property of MatDialogConfig. The position property accepts DialogPosition instance.
The DialogPosition overrides dialog position. It has four optional properties.
top : Override top position.
bottom : Override bottom position.
left : Override left position.
right : Override right position.

The values of above properties can be set in px, em, % etc. To keep dialog on top and in right position, we use postion property of MatDialogConfig as following.
this.dialogRef =,
	data: this.user, 
	height: '350px', 
	width: '250px', 
	position: {right:'10px', top: '10px'} 
The position of dialog can be configured as following.
1. Dialog on top-right.
{top: '0px', right:'0px'} 
2. Dialog on top-left.
{top: '0px', left:'0px'} 
3. Dialog at bottom-right.
{bottom: '0px', right:'0px'} 
4. Dialog at bottom-left.
{bottom: '0px', left:'0px'} 
5. Dialog on top-middle.
6. Dialog at bottom-middle.
7. Dialog in right-middle.
8. Dialog in left-middle.

Note: Using the combination of left/right and top/bottom properties, we can set dialog position anywhere in the display area.

5. Complete Example

A. Dialog Opener Component

import { Component } from '@angular/core';
import { MatDialog, DialogPosition } from '@angular/material/dialog';
import { UserDialogComponent } from './user-dialog.component';
import { User } from './user';

  selector: 'example-dialog',
  templateUrl: './example-dialog.component.html',
export class ExampleDialogComponent {
  user = { name: '', city: '' };
  dialogRef: any;

  constructor(public dialog: MatDialog) { }

  openUserDialog() {
    this.dialogRef =,
        data: this.user,
        height: '350px',
        width: '250px',
        position: { right: '10px', top: '10px' }

    this.dialogRef.afterClosed().subscribe((result: User) => {
      console.log('The User dialog was closed.');
      console.log(result?.name + ' - ' + result?.city);
<h2>Dialog Demo</h2>
  <button mat-raised-button (click)="openUserDialog()">Pick user</button>
  <br /> {{}}
  <br /> {{}}
B. Dialog Component

import { Component, Inject } from '@angular/core';
import { MatDialogRef, MAT_DIALOG_DATA } from '@angular/material/dialog';

  templateUrl: './user-dialog.component.html',
export class UserDialogComponent {
    public dialogRef: MatDialogRef<UserDialogComponent>,
    @Inject(MAT_DIALOG_DATA) public data: User,
  ) { }
  onCancelUserDialog(): void {
<h2 mat-dialog-title>User Detail</h2>

    <mat-form-field appearance="fill">
      <input matInput [(ngModel)]="" placeholder="Enter city">
<div mat-dialog-actions>
  <button mat-button (click)="onCancelUserDialog()">Cancel</button>
  <button mat-button [mat-dialog-close]="data" cdkFocusInitial>Ok</button>
export interface User {
    name: string;
    city: string;
import { Component } from '@angular/core';

  selector: 'app-root',
  template: `<example-dialog></example-dialog>`
export class AppComponent {
