Custom template(transclusion without ng-content) for list component in Angular2

Question

I have a list component which shows only names. list component should be able to take custom template which will be given by user.

List Component

import {Component } from 'angular2/core';

@Component({
  selector: 'my-list',
  template: `<p>This is List</p>
     <ul>
       <li *ngFor="#i of data"><div class='listItem'>{{i.name}}</div></li>
    </ul>`
})
export class MyList implements OnInit{ 
    data: Array<any> = [{name: 'John', age: 26},{name: 'Kevin', age: 26},  {name:'Simmons', age:26}];
}

My Requirement

<my-list>
   <div>{{i.name}}-{{i.age}}</div> //user should be able to provide custom template like this
</my-list>

I tried this with ng-content but it throws error. In angular 1 same thing used to work with transcluded content. do we have any alternative of manual transclusion in angular 2 and if not then how could we implement this feature in angular2.

You need to use ngForTemplate, I've created PrimeNG DataList and many other DataComponents using this technique and it works great. Demo;

Code;

In your component, define a templateRef with contentchild;

@ContentChild(TemplateRef) itemTemplate: TemplateRef;

Your template becomes;

template: `<p>This is List</p>
     <ul>
       <template ngFor [ngForOf]="data" [ngForTemplate]="itemTemplate"></template>
    </ul>`

So that your users can define content like;

<my-list>
   <template #anything>
        <div>{{anything.i.name}}-{{anything.i.age}}</div>
   </template>
</my-list>
