A Dialog can be nested within another Dialog. The below sample contains parent and child Dialog (inner Dialog).
Step 1:
Create two div elements with id #dialog and #innerDialog.
Step 2:
Initialize the Dialog as mentioned in the below sample.
Step 3:
Set the inner Dialog target as #dialog.
import { Component, ViewChild, OnInit, ElementRef } from '@angular/core';
import { DialogComponent } from '@syncfusion/ej2-angular-popups';
import { EmitType } from '@syncfusion/ej2-base';
@Component({
selector: 'app-root',
template: `
<button class="e-control e-btn" style="position: absolute;" id="targetButton" (click)="onOpenDialog($event)">Open Dialog</button>
<div #container class='root-container'></div>
<ejs-dialog id='dialog' #ejDialog header='Outer Dialog' height='300px' width='400px' showOnInit='true' showCloseIcon='true' [content]='content' [target]='targetElement' [animationSettings]='dialogAnimation' [closeOnEscape]='closeOnEscape'>
<button class="e-control e-btn" id="innerButton" (click)="onOpenInnerDialog($event)" style='margin-left: 18px;'>Open InnerDialog</button>
</ejs-dialog>
<ejs-dialog id='innerDialog' #ejInnerDialog header='Inner Dialog' height='150px' width='250px' showOnInit='true' showCloseIcon='true' content='This is a Nested Dialog' target='#dialog' [animationSettings]='dialogAnimation' [closeOnEscape]='closeOnEscape'>
