angularjs – Angular ui-select不包含在包含在角ui-bootstrap模

我正在面对 anular-ui-bootstrap modal指令的问题.
在我的应用程序中使用角度的 ui-select组件作为html选择的替代.这个ui-select在任何被包含的页面中都可以正常工作.
但是当我试图将它包含在一个模态弹出窗口中(使用ui-bootstrap $modal服务)时,下拉列表不显示选项

问题是here转载

angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl',function ($scope,$modalInstance,items) {
  $scope.addresses = [{
  "id":1,"name": "chennai"
  },{
    "id":2,"name": "banglore"
  },{
    "id":3,"name": "madurai"
  }];
});

<div class="modal-body">
        City
            <ui-select ng-model="selAddress">
                <ui-select-match placeholder="Choose an address">{{$select.selected.name}}</ui-select-match>
                <ui-select-choices repeat="address in addresses track by $index" refresh-delay="0">
                    <div ng-bind-html="address.a | highlight: $select.search"></div>
                </ui-select-choices>
            </ui-select>
            
            Selected: <b>{{ selAddress }}</b>
        </div>

任何帮助将不胜感激.
提前致谢.

<ui-select-choices repeat="..." ng-hide="!$select.open">
