Arguments

:: (xml ~ WidgetFor site (), RenderMessage site FormMessage) |
=> Html | label for the form
-> ([[FieldView site]] -> xml) | how to display the rows, usually either `massDivs` or `massTable`
-> (Maybe a -> AForm (HandlerFor site) a) | display a single row of the form, where `Maybe a` gives the previously submitted value
-> Maybe [a] | default initial values for the form
-> AForm (HandlerFor site) [a] |

Generate a form that accepts 0 or more values from the user, allowing the user to specify that a new row is necessary.
