在angularJS中怎么美化radio

 <p ng-repeat="reason in options.reasons" class="confirm-reason-item">
                <label ng-class="{activeBg: isActive}" ng-click="isActive=!isActive">
                    <input type="radio" ng-model="data.selectedReason" ng-value="reason.desc">{{reason.desc}}
                    <span class="radio-checked"></span>
                </label> 
</p>

我想实现的是只有点击其他时才isactive=false

你要美化需要图片来模拟，自己切换下样式什么的
