65. José Valim @josevalim blog.plataformatec.com Ewwwwww

76. José Valim @josevalim blog.plataformatec.com Ok, what about markup?
77. José Valim @josevalim blog.plataformatec.com SimpleForm is not tied to any markup. Proof?
78. José Valim @josevalim blog.plataformatec.com SimpleForm.setup do |config| config.components = [ :label, :error, :input, :hint ] config.hint_tag = :span config.error_tag = :span config.wrapper_tag = :div end
