I know that with the onSelectionChange()
from the mat-option of the mat-autocomplete i can do something when an option is selected but what i want is for the autocomplete to ADD the value of the mat-option to the input instead of replace its content.
Example:
- input: "hello"
- click mat option " world"
- input: "hello world"
How do i accomplish this without kepping tabs on the form value and stocking its previous value and putting it back (since that just seems like a bad workaround)?
<mat-form-field class="w-100">
<textarea [matAutocomplete]="auto" [value]="hello" matInput></textarea>
<mat-autocomplete #auto="matAutocomplete" >
<mat-option [value]="world">
world
</mat-option>
</mat-autocomplete>
</mat-form-field>
