Multidimensional AngularJS Arrays

Question

I am looking for a way to bind data from a three-dimensional array in an area with my view.

My area (short version) is as follows:

$scope.publicationData = [ 
    { pubId:'1' , pubName:'Level 1 A' , pubCat:[
        { pubCatId:'1' , pubCatName:'Level 2 A', pubSubCat:[ 
            { pubSubCatId:'1' , pubSubCatName:'Level 3 A' }, 
            { pubSubCatId:'2' , pubSubCatName:'Level 3 B' }
            ]
        },
        { pubCatId:'2' , pubCatName:'Level 2 B', pubSubCat:[
            { pubSubCatId:'3' , pubSubCatName:'Level 3 C' },
            { pubSubCatId:'4' , pubSubCatName:'Level 3 D' }
            ]
        }
        ]
    }];

In the view, I have code that successfully represents what is in the first and second dimensions of the array, but I cannot get the values ​​from pubSubCatId or pubSubCatName

HTML + Angular View

<div ng-controller="myPublictionCtrl">

<div ng-repeat="publication in publicationData">

    <ul>
        <li >
                            <!-- This works -->
            {{publication.pubId}}. {{publication.pubName}}
        </li>
    </ul>

    <ul>
                    <!-- This works -->

        <li ng-repeat="category in publication.pubCat">
            {{category.pubCatId}}. {{category.pubCatName}}
        </li>

    </ul>

    <ul>
                    <!-- This doesn't work -->

        <li ng-repeat="subcategory in publication.pubCat.pubSubCat">
            {{subcategory.pubSubCatName}}
        </li>
    </ul>
</div>
</div>

How to get data from deeper layers of an area. Can AngularJS do this?

Answer 1

The third loop should be nested inside the second and use

subcategory in category.pubSubCat

Answer 2

<div ng-controller="myPublictionCtrl">
        <div ng-repeat="publication in publicationData">
            <ul>
                <li style="text-align:left">                       
                    {{publication.pubId}}. {{publication.pubName}}
                </li>
            </ul>
            <ul>
                <li ng-repeat="category in publication.pubCat" style="text-    align:left">{{category.pubCatId}}. {{category.pubCatName}}               
                <ul> 
                <li ng-repeat="subcategory in category.pubSubCat" style="text-align:left">{{category.pubCatId}}.{{subcategory.pubSubCatId}}.     {{subcategory.pubSubCatName}}
                </li>
                </li>
                </ul>
            </ul>
        </div>
    </div>
