如何在Angular.js中使用内部div修复单选窗体

<div ng-app="myApp" ng-controller="myCtrl">
  <div ng-repeat="option in options">
    <input type="radio" ng-model="selectedOption" ng-value="option">{{ option }}
  </div>
</div>

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
  $scope.options = ['Option 1', 'Option 2', 'Option 3'];
  $scope.selectedOption = 'Option 1';
});

div {
  display: inline-block;
  margin-right: 10px;
}
