**Tip**: While you can set `emptyValue` to a non-string value (e.g. `0`), you cannot use `null` or `undefined`, as it would turn the `<AutocompleteArrayInput>` into an [uncontrolled component](https://react.dev/learn/sharing-state-between-components#controlled-and-uncontrolled-components). If you need the empty choice to be stored as `null` or `undefined`, use [the `parse` prop](./Inputs.md#parse) to convert the default empty value ('') to `null` or `undefined`, or use [the `sanitizeEmptyValues` prop](./SimpleForm.md#sanitizeemptyvalues) on the Form component.
