当我打开模态对话框并尝试关闭面板时,将打开第一个自动完成控件的选择面板,如下所示:

html:

<mat-form-field>
  <input
    #autoCompleteInput
    matInput
    type="text"
    [matAutocomplete]="auto"
  >
  <mat-autocomplete #auto="matAutocomplete" autoActiveFirstOption="true" [displayWith]="displayFn">
    <mat-option *ngFor="let option of filteredOptions | async" [value]="option">
      {{option.name}}
    </mat-option>
  </mat-autocomplete>
</mat-form-field>

ts:

//@ViewChild('autoCompleteInput', { read: MatAutocompleteTrigger }) autoComplete: MatAutocompleteTrigger; 
// I also tried this
@ViewChild(MatAutocompleteTrigger) autoCompleteInput: MatAutocompleteTrigger;

ngAfterViewInit() {
  debugger;
  this.autoCompleteInput.closePanel();
}

但不幸的是,第一个自动完成的面板是在对话框加载时打开的。如何防止面板打开,或者如果不可能,关闭面板?
