title: Kendo dropdown list popup height not working
body: <p>In this <a href="https://stackblitz.com/edit/angular-qoygtz?file=app/app.component.ts" rel="nofollow noreferrer">StackBlitz</a> I have a Kendo for Angular dropdown list with a popup height set to 20px. Still, when I open the dropdown list the popup height remains unchanged. How to make this work?</p>
  
  <pre><code>@Component({
  selector: 'my-app',
  template: `
   &lt;kendo-dropdownlist [data]="listItems" [popupSettings]="{ height: 20 }"&gt;
   &lt;/kendo-dropdownlist&gt;
  `
  })
  export class AppComponent {
    public listItems: Array&lt;string&gt; = ["Item 1", "Item 2", "Item 3", "Item 4"];
  }
  </code></pre>
