any better way to write this ?

$(this).parent().parent().find(" dd ul").toggle();

update..

I am trying to create a dropdown using the script here http://www.jankoatwarpspeed.com/post/2009/07/28/reinventing-drop-down-with-css-jquery.aspx

however the script works only for one instance of list and my code works good for multiple instances. Just curious if there is another better way to get parent of a parent in jQuery
