[Vuejs]-V-chip-group value is undefined

You can watch the value and then reset it, but I’m wondering why you want this behaviour? Is it because you need to evaluate if the value is -1 so that you can do something else? I’m asking because I feel it makes sense for the component to set its value to ‘undefined’ when it is deselected.

data() {
  return {
    selectedItem: -1
  };
},
watch: {
  selectedItem(v) {
    console.log(v);
    if (!v) {
      this.selectedItem = -1;
    }
  }
}
