Legacy version of FormLayout that resembles Vaadin 7/8's FormLayout API as closely as possible in order to facilitate migration to newer versions of Vaadin.

FormLayout is used to layout fields. FormLayout is a close relative of VerticalLayout, but in FormLayout captions are rendered to the left of their respective components.
