Description

When combining chips with the autocomplete component the input field isn't cleared between each entry. Despite setting the input fields value to a empty string at the end of my function that is invoked by the optionSelected event.

Reproduction

StackBlitz link: https://stackblitz.com/edit/2qghuqyq?file=src%2Fexample%2Fchips-autocomplete-example.ts
(stackblitz fetched from the Chips Autocomplete example at https://material.angular.io/components/chips/examples)
Steps to reproduce:

  1. Enter a few characters to start filtering the autocomplete list
  2. Select an item on the list by using your mouse

Expected Behavior

After clicking an item from the autocomplete list the input field should be cleared

Actual Behavior

The value in the input field is unchanged

Environment

  • Angular: 19
  • CDK/Material: 19
  • Browser(s): Edge
  • Operating System (e.g. Windows, macOS, Ubuntu): Linux (RHEL 8)

A workaround for this issue is described here: #8214 (comment)

  • Add a reference to the input-element
  • Run input.value = '' after your optionSelected function like this:

<mat-autocomplete #auto="matAutocomplete" (optionSelected)="select($event); input.value = ''" [displayWith]="displayFn">

We should update the doc example to clear the input, but we shouldn't change the component's behavior itself since some apps may want to keep the text.
