Answer 1

In your script:
OrderCtrl = function ($scope) {
$scope.deliveries = [{
name: "RussianPOST",
tax: [{
town: "Moscow",
price: 10,
}, {
town: "Izhevsk",
price: 30,
}]
}, {
name: "DHL",
tax: [{
town: "Moscow",
price: 50,
}, {
town: "Izhevsk",
price: 100,
}]
}
];
$scope.selectedDelivery = $scope.deliveries[0];
$scope.TaxSelect=function(tax){
$scope.selectedTax = tax;
}
}
Your option (I am not sure if ng-model is needed here, but i am letting it stay):
<option ng-repeat="tax in delivery.tax" ng-value="tax" ng-model="$parent.selectedTax" ng-click="TaxSelect(tax)">{{tax.town}} {{tax.price}} $</option>
Your display:
Tax delivery: {{ selectedTax.town}}, {{ selectedTax.price}}
