angular
bug(material-autocomplete): keyboard interaction doesn't work properly when using cdk-virtual-scroll-viewport
Reproduction
Use StackBlitz to reproduce your issue: https://stackblitz.com/edit/angular-5rmvpq
Steps to reproduce:
- Click in the input field to open the autocomplete
- On the keyboard click many times on the "down" key or the "up" key
Expected Behavior
If the focus goes beyond the visible viewport, the list should automaticly scroll down/up
Actual Behavior
It just doesn't scroll, and if the end of the actuall renderd items is reached, it comes back to the start and doesn't render new items.
By the way we had to implement a little hack that the virtual viewport is correctly rendert at all. It is the (opened)-Event at the mat-autocomplete you can see in the stackblitz example.
Environment
- Angular: 8.x
- CDK/Material: 8.x
- Browser(s): Tested in Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): Tested with Windows
Any updates on this matter? will it be addressed on any upcoming release?
Thank you!
This is currently unsupported and blocked by https://github.com/angular/components/issues/10122. It's unknown at this time if, once virtual scrolling is supported by mat-autocomplete, users will be able to provide their own cdk-virtual-scroll-viewport.
Hi All,
We have been using Angular 17 and Angular Material 14.2.7 in our application. The same issue exists in the latest version as well. Is it possible to provide a workaround solution or prioritize this issue as high and provide a fix?

I found this in another thread as a workaround, doesn't seem like it'll be fixed anytime soon unfortunately. https://www.npmjs.com/package/ngx-virtual-select-field
