    # = Action View Form Tag \Helpers
    #
    # Provides a number of methods for creating form tags that don't rely on an Active Record object assigned to the template like
    # FormHelper does. Instead, you provide the names and values manually.
    #
    # NOTE: The HTML options <tt>disabled</tt>, <tt>readonly</tt>, and <tt>multiple</tt> can all be treated as booleans. So specifying
    # <tt>disabled: true</tt> will give <tt>disabled="disabled"</tt>.

      # Starts a form tag that points the action to a URL configured with <tt>url_for_options</tt> just like
      # ActionController::Base#url_for. The method for the form defaults to POST.
      #
      # ==== Options
      # * <tt>:multipart</tt> - If set to true, the enctype is set to "multipart/form-data".
      # * <tt>:method</tt> - The method to use when submitting the form, usually either "get" or "post".
      #   If "patch", "put", "delete", or another verb is used, a hidden input with name <tt>_method</tt>
      #   is added to simulate the verb over post.
      # * <tt>:authenticity_token</tt> - Authenticity token to use in the form. Use only if you need to
      #   pass custom authenticity token string, or to not add authenticity_token field at all
      #   (by passing <tt>false</tt>).  Remote forms may omit the embedded authenticity token
      #   by setting <tt>config.action_view.embed_authenticity_token_in_remote_forms = false</tt>.
      #   This is helpful when you're fragment-caching the form. Remote forms get the
      #   authenticity token from the <tt>meta</tt> tag, so embedding is unnecessary unless you
      #   support browsers without JavaScript.
      # * <tt>:remote</tt> - If set to true, will allow the Unobtrusive JavaScript drivers to control the
      #   submit behavior. By default this behavior is an ajax submit.
      # * <tt>:enforce_utf8</tt> - If set to false, a hidden input with name utf8 is not output.
      # * Any other key creates standard HTML attributes for the tag.
