Yesod.Form.MultiInput

Description

A module providing a means of creating multiple input forms without the need to submit the form to generate a new input field unlike in MassInput.

Synopsis

data MultiSettings site = MultiSettings {
- msAddClass :: Text
- msErrWidget :: Maybe (Html -> WidgetFor site ())
}
data MultiView site = MultiView {
- mvCounter :: FieldView site
- mvFields :: [FieldView site]
- mvAddBtn :: FieldView site
}
mmulti :: (site ~ HandlerSite m, MonadHandler m, RenderMessage site FormMessage) => Field m a -> FieldSettings site -> [a] -> Int -> MultiSettings site -> MForm m (FormResult [a], MultiView site)
amulti :: (site ~ HandlerSite m, MonadHandler m, RenderMessage site FormMessage) => Field m a -> FieldSettings site -> [a] -> Int -> MultiSettings site -> AForm m [a]
bs3Settings :: MultiSettings site
bs4Settings :: MultiSettings site
