javascript - AngularJS ng-repeat array of arrays

Is it possible to use ng-repeat with an array of arrays?

Here's my view:

<div ng-repeat="item in items">
  <p>{{item}}</p>
  <ul>
    <li ng-repeat="i in item.items">{{i}}</li>
  </ul>
</div>

Here's my controller:

  var app = angular.module('plunker', []);
  app.controller('MainCtrl', function($scope) {
    $scope.items = [
      [1, 2, 3],
      [4, 5, 6],
      [7, 8, 9]
    ]
  });

Here's my Plunker:

How can I output:

1
2
3

4
5
6

7
8
9

Your problem lies with this line:

<li ng-repeat="i in item.items">{{i}}</li>

item.items is undefined because item is an array.

You should enumerate item instead of item.items:

<body ng-controller="MainCtrl">
  <div ng-repeat="item in items">
    <ul>
      <li ng-repeat="i in item">{{i}}</li>
    </ul>
  </div>
</body>

Here's a working Plunk.
