Is it possible to use a prop as a v-model value? - vue.js

Question

Is it possible to use the value of a prop as the input's v-model?
I normally do the following when creating an input:
<template>
<form>
<input v-model="form.email" type="email"/>
</form>
</template>
<script>
export default {
data() {
return {
form: {
email: '',
}
}
}
}
</script>
But now I'm trying to achieve the following where this.myProp is used within the v-model without being displayed as a string on the input:
<template>
<form>
<input v-model="this.myProp" type="email"/>
</form>
</template>
<script>
export default {
props: ['myProp'] // myProp = form.email for example (to be handled in a parent component)
}
</script>

Yes, but while using it in parent component. In child component you need to extract value and #input instead of using v-model (v-model is shortcut for value="" and #input) Here is an example of input with label, error and hint in Vue 3 composition API.
BaseInput.vue
<template>
<div class="flex flex-col">
<label>{{ label }}</label>
<input v-bind="$attrs" :placeholder="label" :value="modelValue" #input="$emit('update:modelValue', $event.target.value)">
<span v-for="item of errors" class="text-red-400">{{ item.value }}</span>
<span v-if="hint" class="text-sm">{{ hint }}</span>
</div>
</template>
<script setup>
defineProps({ label: String, modelValue: String | Number, errors: Array, hint: String })
defineEmits(['update:modelValue'])
</script>
Using v-bind="$attrs" you target where attributes like type="email" need to be applied in child component. If you don't do it, it will be added to the top level DOM element. In above scenario <div>.
ParentComponent.vue
<BaseInput type="email" v-model="formData.email" :label="Email" :errors="formErrors.email"/>
