createFieldArray() function

A dynamic list of fields or forms (§8.5).

const lines = createFieldArray(ctx, (initial?: string) => createField(ctx, initial ?? ''))

add(value) and insert(index, value) pass value to the factory, so a factory that ignores its argument builds every item from its own default.

export declare function createFieldArray<I extends Field<any> | Form<any>>(ctx: Ctx, itemFactory: (initial?: ItemInitial<I>) => I, options?: FieldArrayOptions<I>): FieldArray<I>;

Parameters

Parameter	Type	Description

itemFactory	(initial?: ItemInitial<I>) => I
options	FieldArrayOptions<I>	(Optional)

FieldArray<I>
