【问题描述】：
我正在尝试为英国国家/地区创建一个带有 optgroup 的选择，每个国家/地区都包括一个可以选择的县列表。
我正在尝试使用带有 Angular 的 ng-repeat 来访问数据，我可以为选择中的单级数组执行此操作，但我不确定我是否已正确设置我的县数组这样做，这些县显然没有显示在列表中。
JSFiddle：https://jsfiddle.net/ehtxcwtk/1/.
HTML：
<select data-ng-model="address.county" id="countySelect" material-select watch name="countySelect" class="validate">
<option value="" selected>Select an option</option>
<optgroup label="England">
<option data-ng-repeat="county in counties.england">{{county.name}}</option>
</optgroup>
<optgroup label="Scotland">
<option data-ng-repeat="county in counties.scotland">{{county.name}}</option>
</optgroup>
<optgroup label="Wales">
<option data-ng-repeat="county in counties.wales">{{county.name}}</option>
</optgroup>
<optgroup label="Northern Ireland">
<option data-ng-repeat="county in counties.northernIreland">{{county.name}}</option>
</optgroup>
</select>
