In angular 1 I was able to do something like:
There certainly is a html
only solution in Angular:
<h1>Angular 2 Recursive List</h1>
<ul>
<ng-template #recursiveList let-list>
<li *ngFor="let item of list">
{{item.title}}
<ul *ngIf="item.children.length > 0">
<ng-container *ngTemplateOutlet="recursiveList; context:{ $implicit: item.children }"></ng-container>
</ul>
</li>
</ng-template>
<ng-container *ngTemplateOutlet="recursiveList; context:{ $implicit: list }"></ng-container>
</ul>
Here's a gist.
