def input
  input_html_classes.unshift("string")
  input_html_options[:type] ||= 'text'
  input_html_options[:name] ||= "#{object_name}[#{attribute_name}][]"
  markup = <<-HTML


  <ul class="listing">
  HTML

  collection.each_with_index do |value, index|
    if value.to_s.present?
      markup << field_wrapper_for(value, index)
    end
  end

  markup << field_wrapper_for('', nil)
  markup << '</ul>'
end

#label ⇒ Object

NOTE: There is a one to many relationship between the label and the input elements. Because of this we can’t use the “for” attribute on the label point to the “id” of the input. Instead we use the “aria-labelledby” attribute on the input to point to the “id” on the label.

It would be better to use @builder construct the element but the proper syntax escapes me.
