Nested Templates in Angular 2 [duplicate]

Answer 1

You could try the following solution:

@Component({
  selector: 'DropDownList',
  template: `
   <li *ngFor="let item of items" (click)="handleOnSelect(item)">
    <template [ngTemplateOutlet]="itemWrapper" [ngOutletContext]="{ $implicit: item }">
    </template>
   </li>`
})
export class DropDownListComponent {
  @Input() itemWrapper: TemplateRef<any>;
  @Input() items: any;
  handleOnSelect(item) {
   console.log('clicked');
  }
}

@Component({
  selector: 'DropDown',
  template: `
    <div>
      <ul>
          <DropDownList [items]="items" [itemWrapper]="itemWrapper">
          </DropDownList>
      </ul>
    </div>`
})
export class DropDownComponent {
  @Input() items: string[];
  @ContentChild(TemplateRef) itemWrapper: TemplateRef<any>;
} 

@Component({
  selector: 'my-app',
  template: `
     <DropDown [items]="items">
       <template let-item>
            <h1>item: {{item}}</h1>
       </template>
    </DropDown>
  `
})
export class App { 
   items = ['this','is','a','test'];
}

Plunker Example

The ngTemplateOutlet(^2.0.0-rc.2) directive has the same functionality as your custom directive NgWrapper
