create form on vaadin

in my internship i’m developing a web application using vaadin framework, so i have to create a form that contains combobox,datefiled, textarea components using jpacontainer and i don’t know if i’m right but i’ve noticed that automatic form generation use only textfiled and selectfiled to input entities, so is it possible to integrate those components ( combobox,datefiled, textarea )in automatic form, if not could you please tell me what should i use to create this kind of form. thank’s
