Ion-select doesn't scroll in Ionic 3

问题

This select contains the list of all countries in register form. The point is that the ion-content in the form page is scrollable but select it self is not scrolling. Here is the code:

 <ion-item>
       <ion-select interface="action-sheet" class="select" placeholder="Country">
          <ion-option ngDefaultControl [value]='country.name' *ngFor="let country of countries">{{country.name}}
          </ion-option>
        </ion-select>
       </ion-item>

Why select scroll is not working?

This is a known issue, you can track at https://github.com/ionic-team/ionic/issues/17311#issuecomment-460829890

Ionic have provided a workaround by setting following css in global.scss

.action-sheet-group {
    overflow: auto !important;
}

Hope that helps
