Javascript 我怎样才能使计时器出现在“角度”的下拉列表中？

在上，您可以有一个仅包含计时器选择器的可切换下拉列表。然而，我想为计时器选择器添加一个角度模块，而不是使用普通的引导。您可以使用完成类似的操作，但是，没有列出使用时间选择器完成此操作的示例

我尝试过使用相同的代码，并将提及的NgbDatePicker改为NgbTimePicker，但没有效果。下面的示例生成一个

模板解析错误：

，其中ngbTimepicker未被识别为指令

<div class="input-group">
    <input class="form-control" name="startTime" [(ngModel)]="newEmployeeTime.StartTime" ngbTimepicker 
         #start="ngbTimepicker" [readonly]="true">

    <div class="input-group-append">
        <button class="btn btn-outline-secondary calendar" (click)="startTime.toggle()" type="button"><i 
            class="fa fa-clock"></i></button>
    </div>
</div>

当然，一定有一种不复杂的方法来实现这一点，但我现在似乎想不起来。
