  module Inputs

    # Outputs a simple `<input type="hidden">` wrapped in the standard `<li>` wrapper. This is
    # provided for situations where a hidden field needs to be rendered in the flow of a form with
    # many inputs that form an `<ol>`. Wrapping the hidden input inside the `<li>` maintains the
    # HTML validity. The `<li>` is marked with a `class` of `hidden` so that stylesheet authors can
    # hide these list items with CSS (formtastic.css does this out of the box).
    #
    # @example Full form context, output and CSS
    #
    #   <%= semantic_form_for(@something) do |f| %>
    #     <%= f.inputs do %>
    #       <%= f.input :secret, :as => :hidden %>
