Transtion Effects for Filtered format Results

From semantic-mediawiki.org

I have just installed this extension and I am very impressed with the amount of feature this ext provides. I looked at your sample here: http://aroundisleofwight.info/en/Days_Out . In that sample page, when the results are filtered, the list has a nice transition effect to it. How can add such an effect when the results are filtered?
