为什么angular material select会溢出屏幕 [英] Why angular material select is overflowing the screen

问题描述

我在我的应用程序中使用了角度材质选择，您可以在此处找到

解决方案

您可以覆盖分页器面板的默认 css 以将其放置在屏幕上的任何位置:

::ng-deep .mat-select-panel {位置:固定；底部:0；左:0；高度:300px；宽度:100%；}

根据要放置元素的位置更改类的属性.

I am using angular material select in my application which you can find here https://material.angular.io/components/select/overview. The problem is when we place the select near the bottom of the screen it, and when it is opened, It overflow the screen. This is the screenshot of what I am experiencing. What kind of css is needed to prevant this from happening.

   <mat-select style="margin-bottom: 0px;" placeholder="{{input1.title}}" >
                            <mat-option>None</mat-option>
                                               <mat-option *ngFor="let opt_value of input1.enumNameGroups[grp_value] let i = index" value="{{input1.enumidGroups[grp_value][i]}}" >{{opt_value}}</mat-option>
                                                </mat-optgroup>

      </mat-select>

解决方案

You can override the default css of the paginator panel to place it anywhere on the screen:

::ng-deep .mat-select-panel {
  position: fixed;
  bottom: 0;
  left: 0;
  height: 300px;
  width: 100%; 
}

Change the properties of the class depending on where you want to place the element.
