class Formtastic::Inputs::HiddenInput

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 %>
  <% end %>
<% end %>

<form...>
  <fieldset>
    <ol>
      <li class="hidden">
        <input type="hidden" id="something_secret" name="something[secret]">
      </li>
    </ol>
  </fieldset>
</form>

form.formtastic li.hidden { display:none; }
