Answer 1

i got an answer for this question from github angular please check this https://github.com/angular/angular/issues/27503

Answer:

step1:

i have initialized my template as a new component as like below

template.component.ts

import { Component, Input } from '@angular/core';

@Component({
  selector: 'app-device',
  template: `
  <span *ngIf="dataSource.iconCss" class="e-menu-icon {{dataSource.iconCss}}"></span>
  {{dataSource.header}} {{dataSource.text}}
  <span *ngIf="dataSource.templateHeader" class="e-login-content">
    <button ejs-button cssClass="e-info">Sign In</button>
  </span>
`
})
export class DeviceComponent {
  @Input()
  dataSource: any;
}

Then i have used that component template in my parent component as like below

default.html

<div class="control-section">
	<ejs-menu #menu [items]='dataSource' [fields]='menuFields'>
    <ng-template #template let-dataSource>
      <app-device [dataSource]="dataSource"></app-device>
    </ng-template>
  </ejs-menu>
</div>
