How do i make a nested array in angular

Question

Following the tutorial on docs.angularjs.org, step 2. How do I update this array to a nested one?

This is the basic array:

'use strict';

/* Controllers */

function PhoneListCtrl($scope){
    $scope.phones = [

        {"name" : "Samsung Galaxy S4",
        "snippet" : "Operativsystem : Android 4.2.2"
        }
    ]
}

This illustrates what i want to do:

'use strict';

/* Controllers */

function PhoneListCtrl($scope){
    $scope.phones = [

        {"name" : "Samsung Galaxy S4",
            "snippet" : {"Operativsystem" : "Android 4.2.2",
                            "Skärm" : "4,99 tum",
                            "CPU" : "Quad-core",
                            "Kamera, bak" : "13 MP",
                            "Kamera, fram" : "1,9 MP",
                            "Övrigt" : "Närfältskommunikation (Eng. near field communication, NFC)"
                            }
        }
    ]
}

My current HTML template:

<body ng-controller ="PhoneListCtrl">

<h1>The future of mobile devices</h1>

  <ul>
  <li ng-repeat="phone in phones">
  <h3>{{phone.name}}</h3>
  <p>{{phone.snippet}}</p>
</li>
</ul>

 <p>Total number of phones: 2</p>
</body>

I see that i can use {{phone.snippet.Operativsystem}} to get the first element. But I also want the label Operativsystem to be printed in the HTML, like so:

Operativsystem: Android 4.2.2
Skärm: 4,99 tum
CPU: Quad-core
Kamera, bak: 13 MP Kamera, fram: 1,9 MP
Övrigt: Närfältskommunikation (Eng.near field communication, NFC)

I realize I can just do like below, but that still does not print the "attribute names/keys" in the HTML only the values

  <ul>
    <li ng-repeat="phone in phones">
    <h3>{{phone.name}}</h3>
    <ul>
        <li ng-repeat="key in phone.snippet">
            {{key}}
        </li>
    </ul>
    <p>{{phone.snippet}}</p>
</li>
</ul>

You may nest ng-repeat

<ul>
  <li ng-repeat="phone in phones">
    <h3>{{phone.name}}</h3>
    <p ng-repeat="(key, value) in phone.snippet">{{key}}:{{value}}</p>
  </li>
</ul>

Yeah, this is the behaviour I have and want to change!

defau1t Over a year ago

I think OP needs to print the labels too. Like Operativsystem, Skarm, CPU et-al...

You may get values by ng-repeat="(key, value) in phone.snippet"
