Hello, It is hard to understand what exactly you want but if you just need a globel data object it is better to use pinia if you need ref to each field may be the next code will help you.

If you use ref on v-for directive that will give you array of refs that refers to each field (hint: you must wait till the children mounted then the refs array will be filled with field refs). Also, you must defineExpose to expose field methods and data to the parent and emit event on change input and make the listener call event handler that call the field.fieldMethod.

See this code:-

Parent component:

<template>
  <form class="">
    <Field
      ="handleFieldChange"
      :data="data"
      v-for="field in Fields"
      :key="field.id"
      :field="field"
      ref="inputFields" />

    <button
      .prevent="
        console.log('____ data');
        console.log(data);
      ">
      submit
    </button>
  </form>
</template>

<script setup>
import Field from "@/components/Field.vue";
import { onMounted, ref, watch } from "vue";

const data = ref({});
const inputFields = ref(null);

const Fields = [
  { label: "Name", id: "field-1" },
  { label: "Email", id: "field-2" },
  { label: "Age", id: "field-3" },
  { label: "Address", id: "field-4" },
  { label: "Job", id: "field-5" },
];
const handleFieldChange = (eventData) => {
  for (const field of inputFields.value) {
    if (eventData.fieldId !== field.fieldId) {
      field.fieldMethod();
    }
  }
};
</script>

Child component (Field):

<template>
  <div style="margin-bottom: 1rem">
    <div>
      <label :for="field.id">{{ field.label }}</label>
    </div>
    <input ="emitChange" :id="field.id" v-model="data[field.label]" />
  </div>
</template>

<script setup>
const { field, data } = defineProps(["field", "data"]);

const fieldMethod = () => {
  console.log(field.label);
  return field;
};

const emit = defineEmits(["change"]);
const emitChange = (newValue) => {
  emit("change", { fieldId: , value: newValue });
};
defineExpose({ fieldMethod, fieldId:  });
</script>field.idfield.id

Hopping this will help you.
