Using the v-for directive to loop through a list of items and adding a v-autocomplete with

I am facing a challenge with using a dropdown menu within a loop to select the region for each office in my list of offices. The problem lies in passing the index value to the updateRegion method so that I can correctly associate the selected region with the respective office.

Is there an alternative approach to solve this issue? I'm open to suggestions as I currently do not have a solution.

<template v-for="(office, index) in offices">
        <v-flex xs12 class="mt-3" :key="index">
            <v-card class="white--text">
                <v-card-text>
                    <v-layout row wrap>
                        <v-flex xs12 sm4 pr-2>
                            <v-autocomplete
                                :value="office.region.id"
                                :items="regions"
                                :label="Region"
                                @change="updateRegion"
                            ></v-autocomplete>
                        </v-flex>
                    </v-layout>
                </v-card-text>
            </v-card>
        </v-flex>
    </template>

    <script>
        methods: {
            updateRegion(value) {
                // How can I access the index value here?
            }

If you are looking to retrieve the index of the office and the chosen value from the v-autocomplete within your updateRegion function, you can achieve this by passing the office.regio.id and index as parameters.

I have not had a chance to test it yet. If it does not work as expected, please inform me.

    <v-flex xs12 class="mt-3" :key="index">
        <v-card class="white--text">
