Quite simple for now: create a folder and place objects inside !-)

You mean a menu of links, or a select in a field ?

news.objectValues(['event']) method will give you the list of objects
with meta_type 'event' contained in the folder with id 'news'. So
Andrew's answer was almost ok:

<tal:block define="news python: context.news.objectValues(['event']" >
<ul tal:condition="news" tal:repeat="new news" >
  <li>
    <a tal:attributes="href news/absolute_url"
       tal:content="news/title">Link</a>
  </li>
</ul>
</tal:block>

(replace html markup with what appropriate of course...)

NB: see also objectIds() and objectItems() in the doc.
