在home.html中，我已包含popover页面。我面临的问题是，其中包含很多内容，并且没有显示任何滚动条并退出页面。

如何获得页面上的滚动条？下面是我的home.html页面和popover的屏幕截图。

下面是popoverpage.html代码：

<ion-content padding>
  <ion-grid fixed>
    <ion-row>
<!-- <ion-col size="12">
  This is example of popup
</ion-col> -->
    </ion-row>
    <ion-row>

<ion-col size="12">
  <ion-button (click)="closepopup()" expand="block" fill="clear" shape="round" color="danger">
    Close
  </ion-button>
</ion-col>


</ion-row> 


<!--change stage starts-->
<ion-item (click)="changestage()">
  <ion-label>Change Stage</ion-label>
</ion-item>
<br>

<ion-list *ngIf="showstage == true">
  <ion-item> 
    <ion-label>Lead Stage</ion-label>
    <ion-select  okText="Okay" cancelText="Dismiss" [(ngModel)]="dropdown2" >
      <ion-select-option *ngFor="let list of leadstagelist" value="{{list.name}}" checked="true">

查看添加这些全局css规则是否可行

  .backdrop-no-scroll ion-content {
    --overflow: hidden;
  }
  .backdrop-no-scroll ion-backdrop+* ion-content {
    --overflow: visible;
  }
