Type Alias: MoveFieldValueFn<TFormData>#

type MoveFieldValueFn<TFormData> = <TFieldName>(arrayFieldName, fromIndex, toIndex, options?) => void;

Defined in: FormApi/FormApiArrayMethods.types.public.ts:129

Moves an element to another index in an array field.

Passing equal indices does nothing. Invalid indices or a runtime value that is not an array produce a warning and leave the value unchanged.

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