I have a input box in html using mat-autocomplete, which filtered out the list on value changes, which is working fine. Actually I want to auto set the last remaining value of the array to the input box, which also is working fine, but the problem is I am unable to clear the value in the input box in browser using backspace after setting the value. Below is the code shortened for clarity.



<mat-form-field>
<input formControlName="charge" name="charge" matInput placeholder="charge" [matAutocomplete]="auto">
<mat-autocomplete #auto="matAutocomplete">
<mat-option *ngFor="let option of filteredOptions | async" [value]="option">
option
</mat-option>
</mat-autocomplete>
</mat-form-field>


and in .ts file



filteredOptions: Observable<string[]>;
options: ['one', 'two', 'three', 'four', 'five', 'six'] // for demo purpose
filteredArr;

ngOnInit()
this.filteredOptions = this.myForm.get('charge').valueChanges
.pipe(map(value => this._filter(value)));


private _filter(val)
const filterValue = val.toLowerCase();
this.filteredArr = this.options.filter(option => option.toLowerCase().includes(filterValue));
if(this.filteredArr.length == 1)
// tried with setValue too, same result
this.myForm.get('charge').patchValue(this.filteredArr[0], emitEvent: false);
this.filteredArr = [];
return this.filteredArr;

return this.filteredArr;



Thanks in advance. Let me know if required more information.
