Description

I have several autocomplete input fields in my form. But i would like to be able to be able to close the panel programmatically.
When i set the focus to another fields programmatically. The autocomplete-panel doesn't close.

In the material documentation is stated that to do this you need to use the MatAutocompleteTrigger, but I'm unable to get a reference to it. I can however find a reference to the MatAutocomplete itself. But the trigger isn't exposed.

In the code i've found this way to get to my component:

this.componentService.getFormControlRef('fieldID').instance.matAutocomplete);

In DynamicMaterialInputComponent i find following line:

@ViewChild("matAutocomplete", {static: true}) matAutocomplete: MatAutocomplete;

But I think to achieve this, another line should be added, something like this.

@ViewChild('autoCompleteInput', { read: MatAutocompleteTrigger }) autoComplete: MatAutocompleteTrigger

Would this be possible, or is there another way to achieve closing the autocomplete-panel programmatically.

Thanks in advance,

Bart
