递归模板Angular2

Question

How can I do recursive template with Angular 2 without ng-include. I don't understand why Angular 2 won't include this skill...

HTML:

<div ng-app="app" ng-controller='AppCtrl'>
<script type="text/ng-template" id="categoryTree">
    {{ category.title }}
    <ul ng-if="category.categories">
        <li ng-repeat="category in category.categories" ng-include="'categoryTree'">           
        </li>
    </ul>
</script>
<ul>
    <li ng-repeat="category in categories" ng-include="'categoryTree'"></li>
</ul>    

JS:

 var app = angular.module('app', []); app.controller('AppCtrl', function ($scope) { $scope.categories = [ { title: 'Computers', categories: [ { title: 'Laptops', categories: [ { title: 'Ultrabooks' }, { title: 'Macbooks' } ] }, { title: 'Desktops' }, { title: 'Tablets', categories: [ { title: 'Apple' }, { title: 'Android' } ] } ] }, { title: 'Printers' } ]; }); 

Answer 1

Use ngFor instead of ng-repeat in Angular2.
