v-autocompleteをVuetify2からVuetify3に移行してみました。
選択肢に選択している値が無くても表示されるようなったり、
イベントが整理され、mousedownやchange、blurを使って頑張らなくても、
update:menuが追加されたりと、使いやすくなっています。
Vuetify2 → Vuetify3
(Vuetify2)v-autocomplete：無駄なAPIリスクエストをせずにサジェストを表示する
↓
※color="primary"追加すれば青色にできます。
avatarはデフォルトのを使うようにして、コードも表示するようにしてみました。
Options APIのまま移行
※item-text, item-value, placeholderは直指定に変更しています。
