angularjs ng-options键值对3级深

Question

我有一个问题，我无法在ng-options中制作3级深度，我能够将工作深入到2级

这是我的代码

控制器

$scope.names = {
            'Technology': [
                'Personal Computer',
                'Mobile Phone',
                'Console Game'
            ],
            'Healthcare': [
                'Blood Donation',
                'Injection',
                'Medical Care'
            ],
            'Housing': [
                'Repairs',
                'Gardening',
                'Plumbing',
                'Laundry'
            ]    
        };

HTML

<select ng-model="selectedName" ng-options="x for (x, y) in names">
</select>

<select ng-model="selectedNames" ng-options="x for x in selectedName">
</select>

这是有效但只有2级深，我需要的是3级深度。

所以$ scope.names就像这样

控制器

$scope.names = {
            'Technology': [
                'Personal Computer': [
                    'some data', 
                    'some data'
                    ],
                'Mobile Phone': [
                    'some data', 
                    'some data'
                    ],
                'Console Game': [
                    'some data', 
                    'some data'
                    ]
            ],
            'Healthcare': [
                'Blood Donation': [
                    'some data', 
                    'some data'
                    ],
                'Injection': [
                    'some data', 
                    'some data'
                    ],
                'Medical Care': [
                    'some data', 
                    'some data'
                    ]
            ],
            'Housing': [
                'Repairs': [
                    'some data', 
                    'some data'
                    ],
                'Gardening': [
                    'some data', 
                    'some data'
                    ],
                'Plumbing': [
                    'some data', 
                    'some data'
                    ],
                'Laundry': [
                    'some data', 
                    'some data'
                    ]
            ]    
        };

我如何安排我的ng选项？它没有使用ng-options="x for (x, y) in names"
