+-- @\<input\>@ tags in Bootstrap 3 require the @form-control@ class,
+-- and so they need modified 'FieldSettings' to display correctly.
+--
+-- When creating your forms, use the 'bfs' function to add this class:

+-- > personForm = Person
+-- >        <$> areq textField (bfs ("Name" :: Text)) Nothing
+-- >        <*> areq textField (bfs ("Surname" :: Text)) Nothing

+-- That form can then be rendered into a widget using the 'renderBootstrap3' function. Here, the form is laid out vertically using 'BootstrapBasicForm':
+--
+-- > (formWidget, formEnctype) <- generateFormPost $ renderBootstrap3 BootstrapBasicForm personForm
+--
+-- And then used in Hamlet:
+--
+-- >  <form role=form method=post action=@{ActionR} enctype=#{formEnctype}>
+-- >    ^{formWidget}
+-- >    <button type="submit" .btn .btn-default>Submit
+
+-- $example2
+-- Yesod.Form.Bootstrap3 also supports <http://getbootstrap.com/css/#forms-horizontal horizontal, grid based forms>.
+-- These forms require additional markup for the submit tag, which is provided by the 'bootstrapSubmit' function:
+--
+-- > personForm :: AForm Handler Person
+-- > personForm = Person
+-- >        <$> areq textField MsgName Nothing
+-- >        <*> areq textField MsgSurname Nothing
+-- >        <*  bootstrapSubmit (BootstrapSubmit MsgSubmit "btn-default" [("attribute-name","attribute-value")])
+-- >        -- Note: bootstrapSubmit works with all BootstrapFormLayouts, but provides the additional markup required for Bootstrap's horizontal forms.
+--
+-- That form can be rendered with specific grid spacing:
+--
+-- > (formWidget, formEnctype) <- generateFormPost $ renderBootstrap3 (BootstrapHorizontalForm (ColSm 0) (ColSm 4) (ColSm 0) (ColSm 6)) personForm
+--
+-- And then used in Hamlet. Note the additional @form-horizontal@ class on the form, and that a manual submit tag isn't required:

+-- >    ^{formWidget}

+-- This module comes with several methods to help customize your Bootstrap 3 @\<input\>@s.

+-- >        <$> areq textField nameSettings Nothing
