Question

Vue.js

How to use the item-value option in vuetifyjs (v-autocomplete component) if you use a function in it? I’m already hitting the table, I’ve bruised my whole forehead, I don’t understand how to use it when the function type is selected.

The function itself can be a component method:
:item-value="itemValue"

methods: {
  itemValue() {
    ...

UPD. Still unclear? Well, here's a small example for you (made on the basis of the first demo from the documentation).
