javascript - Angularjs Multidimensional array and two relative select boxes -

i have multidimensional array holds product names , versions. want create interface lets user select product select box, , version number in second select box. second select box should show versions numbers of product user selected in first select box.

this mutidimensional array:

[object]0:           name: "product 1"          versions: [array]0:                            number: "1.0"                            number: "1.5.2"         1:           name: "product 2"          versions: [array]0:                            number: "0.0"                            number: "0.5" 

the user has option choose multiple products, created array hold users selection.

my controller setup this:

app.controller('maincontroller', function ($scope) {      $scope.products = [{id: 1, name: '', versions: []}];    $scope.packages = [];   $scope.packages[0] = { id: 1, name: 'product 1', versions: [{number: 1.0}, {number: 1.5}, {number: 2.0}]};   $scope.packages[1] = { id: 2, name: 'product 2', versions: [{number: 0.1}, {number: 0.2}, {number: 0.3}]};      $scope.addproduct = function(){     var id = $scope.products.length + 1;     $scope.products.push({id: id, name: "", version: []});    }; }); 

and select boxes setup angularjs:

    <div  ng-repeat="product in products">        <label>product</label>        <select ng-model="product.product" ng-options="package.name package in packages" class="form-control"></select>         <label>version</label>        <select ng-model="product.versions" ng-options="version.number version in product.versions" class="form-control"></select> </div> <button ng-click="addproduct()">add product</button> 

what tried setup ng-options select versions object of current product. doesn't work.

i created jsfiddle of have: http://jsfiddle.net/rkyu4rjq/
