Answer 1

<ul>&nbsp; &nbsp; <li ng-repeat="item in items" ng-include="'item.html'"></li></ul><script type="text/ng-template" id="item.html">&nbsp; &nbsp; {{item.title}}&nbsp; &nbsp; <ul>&nbsp; &nbsp; &nbsp; &nbsp; <li ng-repeat="item in item.sub" ng-include="'item.html'"></li>&nbsp; &nbsp; </ul></script>来自一段项目代码，自己体会。
