Angular 可滚动垫选择列表？

Question

我有一个问题。我没有在堆栈上发现任何熟悉的问题所以我在这里问，是否可以使 <mat-selection-list> 可滚动（Angular 7）？当项目太多无法容纳 window.

时，我想在右侧显示滚动条

<mat-card fxFlex="33%">
<mat-selection-list>
  <mat-list-item
    *ngFor="let product of products"
    [class.selected]="product === selectedproduct"
    (click)="onSelect(product)"
  >
  </mat-list-item>
</mat-selection-list>

Answer 1

您可以试试：

<mat-card fxFlex="33%">
     <mat-selection-list [style.overflow]="'auto'" [style.height.px]="'300'">
         <mat-list-item
              *ngFor="let product of products"
              [class.selected]="product === selectedproduct"
              (click)="onSelect(product)"> 
     </mat-list-item>
</mat-selection-list>

通过设置自定义 CSS 属性？

CSS 只支持 Chrome 浏览器的精美滚动条：

.custom-scroll-bar{
    height:70vh;
    overflow-y:scroll;
    overflow-x: hidden;
}

.custom-scroll-bar::-webkit-scrollbar{
    width: 5px;
}

.custom-scroll-bar::-webkit-scrollbar-thumb{
    background: rgba(0,0,0,.26);
}

对于 Firefox 和 Internet Explorer 只需简单地使用：

.custom-scroll-bar{
    height:70vh;
    overflow-y:scroll;
}

HTML:

<mat-selection-list #shoes class="custom-scroll-bar">
  <mat-list-option *ngFor="let shoe of typesOfShoes">
    {{shoe}}
  </mat-list-option>
</mat-selection-list>
