# RemoveFieldValueFn

# Type Alias: RemoveFieldValueFn\<TFormData\>

```ts
type RemoveFieldValueFn<TFormData> = <TFieldName>(arrayFieldName, index, options?) => void;
```

Defined in: [FormApi/FormApiArrayMethods.types.public.ts:247](https://github.com/TanStack/form/blob/main/packages/form-core/src/FormApi/FormApiArrayMethods.types.public.ts#L247)

Removes an element from an array field.

An invalid index or a runtime value that is not an array produces a warning
and leaves the value unchanged.

By default, the update marks the array field as touched and dirty, notifies
change listeners, and runs change validation.

### index

### options?
