需要有角度的材料下拉面板才能有向下和向上箭头按钮

angular-material angular css

CPK_2011 · 技术社区 · 10 月前

我正在使用 Angular 15 , Angular Material 14 和 CSS

我几乎已经完成了这个样品的工作。。

我正在使用 -webkit-scrollbar 从此链接- Orangeable Scrollbars

使用的代码如下。。。

<mat-select disableOptionCentering (selectionChange)="validateInputs(userForm)" formControlName="siteId" placeholder="Select Site ID" panelClass="custom-panel-siteId">

.custom-panel-siteId {
  margin: 40px 0px !important;
  min-width: 313px !important;
  margin-left: 17px !important;
  border-radius: 5px;
}

.custom-panel-siteId::-webkit-scrollbar {
  border-radius: 5px;
}

.custom-panel-siteId::-webkit-scrollbar-track {
  border-radius: 5px;
  background-color: rgba(242, 242, 242);
}

.custom-panel-siteId::-webkit-scrollbar-thumb {
  border-radius: 5px;
  background-color: rgba(211, 211, 211);
}

输出是这样的。。。

我只需要补充一下 Down 和 Up 滚动条的箭头。

我怎样才能做到这一点?

看完这个 codepen 我终于找到了合适的滚动条来解决这个问题!

export class AppComponent {
  constructor() {}

  countries: any = [
    {
      full: 'Great Britain',
      short: 'GB',
    },
    {
      full: 'United States',

      full: 'United States',

    },
    {
      full: 'Canada',
      short: 'CA',
    },
  ];
  selectedCountry: string = 'GB';

  selectedCountryControl = new FormControl(this.selectedCountry);
}

默认情况下,垫子选择上下箭头
