module Select2Helper
  # @example

  #   select2 /^Item/, from: "select_id"

  def select2(text, options)
    find("#s2id_#{options[:from]}").click
    all(".select2-result-label").find do |result|
      result.text =~ Regexp.new(text)
    end.click
  end

I wrapped the code which selects options from select2 into a gem capybara-select-2
