FieldArray v4.5

Form Context

The <FieldArray /> component requires being used inside a Form component or a useForm to be called at its parent tree.

The <FieldArray /> component is used to manage repeatable array fields. It is a renderless component, meaning it doesn't render anything of its own.

  <Form @submit="onSubmit" :initial-values="initialValues">
    <FieldArray name="links" key-path="id" v-slot="{ fields, push, remove }">
      <div v-for="(field, idx) in fields" :key="field.key">
        <Field :name="`links[${idx}].url`" type="url" />

        <button type="button" @click="remove(idx)">Remove</button>

      <button type="button" @click="push({ id:, name: '', url: '' })">Add</button>


export default {
  data: () => ({
    // you can set initial values for those array fields
    initialValues: {
      links: [{ id: 1, url: '' }],
  methods: {
    onSubmit(values) {
      alert(JSON.stringify(values, null, 2));

API Reference


arrayPathstringYesThe form array path you wish to manage



The default slot gives you access to the following props:

fields: FieldArrayEntry<TValue>

This is a read-only version of your array items, wrapped inside a FieldArrayEntry object which has the following interface:

tsinterface FieldEntry<TValue = unknown> {
  // The actual value of the item, this is what exists in the form values
  value: TValue;
  // a value you can use as a key for iteration, generated by `key-path` prop
  key: string | number;
  // true if this is the first array item
  isFirst: boolean;
  // true if this is the last array item
  isLast: boolean;

push(item: any)

Adds an item to the end of the array.

prepend(item: any)

Adds an item to the start of the array.

remove(idx: number)

Removes the item at the specified index from the array if it exists.

swap(idxA: number, idxB: number)

Swaps the items at the given indexes with each other. Both indexes must exist in the array or it won't have an effect.

insert(idx: number, item: any)

Adds an item at the specified index. If the specified index will place the item out of bounds (i.e: larger than length) the operation will be ignored, you still can add items as the last item of the array.

update(idx: number, value: any)

Updates the value at the specified index, note that it doesn't merge the values if they are objects. If the specified index is outside the array boundary the operation will be ignored.

replace(items: any[])

Replaces the entire array of fields.
