You can include an RSS Feed widget anywhere in the main content area of your
  page by including an empty div element with the id wdn_rss_widget
  and including the plugin initialization (which will include the "UNL In The News"
  RSS news feed):
WDN.initializePlugin('rss_widget');
To get the default stylization of the plugin, you also need to give it the
  style class wdn-rss-widget.
Alternatively, you can load the RSS widget with your own RSS feed by providing a URL as the second parameter:
WDN.initializePlugin('rss_widget', 'http://newsroom.unl.edu/announce/cse?format=xml');
You can also customize a few things by providing a JavaScript object like this:
WDN.initializePlugin('rss_widget', { url:'http://newsroom.unl.edu/announce/cse?format=xml',
                                     elementId: 'wdn_rss_widget', 
                                     pause: 8000,
                                     limit: 10,
                                     num_show: 3});
Where each attribute is as follows:
wdn_rss_widget)
  The widget has been updated to allow multiple RSS widget feeds in the same
  page.  You can achieve this by providing an array of JavaScript
  configuration objects:
WDN.initializePlugin('rss_widget', [
  {
    url: 'http://ucommxsrv1.unl.edu/rssfeeds/unlinthenewsrss.xml',
    elementId : 'wdn_rss_widget',
    pause: 5000,
    limit: 8,
    num_show: 4
  },
  {
    url: 'http://newsroom.unl.edu/announce/cse/?format=rss',
    elementId : 'wdn_rss_widget_cse',
    pause: 10000,
    limit: 10,
    num_show: 2
  }]);
Note that if you use multiple RSS feed widgets, you should provide distinct 
elementIds for each one.  Moreover, each div should have the style
class, wdn-rss-widget added to it to receive the same styling.
You can stylize your rss widget(s) further by adding zenbox style classes:
<div id="wdn_rss_widget" class="wdn-rss-widget zenbox primary"></div>
Possible options for the subclasses: bright, cool, energetic, neutral, primary, soothing (see the zenbox documentation for the colors these themes correspond to).
