Angularjs: Cascade Dropdown

I'm trying to achieve a cascade dropdown in Angular. I thought it would just work naturally thanks to binding. See below: Copy it's just that I hadn't put the filter at the right place... silly mistake. Solution 2: It could be that your selectedRequest.client does not refer to the same object in clients array. Try this: JS: function testController($scope) { $scope.clients = [ { id: 1, name: "client1", departments: [{ id: 1, defaultLabel: 'department1' }, { id: 2, defaultLabel: 'department2'}] }, { id: 2, name: "client2", departments: [{ id: 3, defaultLabel: 'department3' }, { id: 4, defaultLabel: 'department4'}] } ]; $scope.selectedRequest = {}; $scope.selectedRequest.client = $scope.clients[0];//Assign by object reference. } Copy HTML: <div ng-controller="testController"> <select name="client" ng-model="selectedRequest.client" ng-options="c.name for c in clients" required></select> <select id="department" ng-model="selectedRequest.department" ng-options="d.defaultLabel for d in selectedRequest.client.departments"></select> </div> Copy DEMO I removed track by to use the default (track by object reference) and ensure that selectedRequest.client refers to objects inside clients Share Post a Comment for "Angularjs: Cascade Dropdown" Top Question Edit A Txt File Using Javascript/jquery I want to modify a .txt (overwrite completely) using javasc… How To Include Highcharts Motion Plugin For Bubble Plot Using R Wrapper?
