To open multiple mdDialog boxes (also known as Angular Material Dialog) in an Angular application, you can follow these steps:

  1. Import the required Angular Material modules and components:

In your app.module.ts file, make sure you have imported and added the required Angular Material modules to the imports array, such as MatDialogModule and MatButtonModule:

import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { BrowserAnimationsModule } from '@angular/platform-browser/animations'; import { MatDialogModule } from '@angular/material/dialog'; import { MatButtonModule } from '@angular/material/button'; import { AppComponent } from './app.component'; @NgModule({ declarations: [AppComponent], imports: [ BrowserModule, BrowserAnimationsModule, MatDialogModule, MatButtonModule, ], providers: [], bootstrap: [AppComponent], }) export class AppModule {}
  1. Create and define your dialog components:

For each dialog you want to open, create a separate Angular component that represents the dialog's content and behavior. These components should use MatDialogRef to control the dialog's opening and closing.

import { Component } from '@angular/core'; import { MatDialogRef } from '@angular/material/dialog'; @Component({ selector: 'app-dialog-component1', template: ` <!-- Dialog content here --> <h1>Dialog Box 1</h1> <button mat-button (click)="closeDialog()">Close</button> `, }) export class DialogComponent1 { constructor(private dialogRef: MatDialogRef<DialogComponent1>) {} closeDialog() { this.dialogRef.close(); } }

Similarly, create more components for other dialogs (e.g., DialogComponent2, DialogComponent3, etc.).

  1. Inject the MatDialog service into your main component:

In the component from which you want to open the dialogs (e.g., AppComponent), inject the MatDialog service.

import { Component } from '@angular/core'; import { MatDialog } from '@angular/material/dialog'; import { DialogComponent1 } from './dialog-component1.component'; import { DialogComponent2 } from './dialog-component2.component'; @Component({ selector: 'app-root', template: ` <button mat-button (click)="openDialog1()">Open Dialog 1</button> <button mat-button (click)="openDialog2()">Open Dialog 2</button> `, }) export class AppComponent { constructor(private dialog: MatDialog) {} openDialog1() {; } openDialog2() {; } }
  1. Add buttons or triggers to open the dialogs:

In your template (e.g., app.component.html), add buttons or triggers that call the openDialog1() and openDialog2() methods from your AppComponent to open the respective dialogs.

Now, when you click the buttons, the corresponding dialogs (DialogComponent1 and DialogComponent2) will open. You can repeat the process for additional dialogs as needed.

Remember to customize the content and behavior of each dialog component according to your requirements.
