Sons of suckerfish dropdown IE fix

Published in: JavaScript 

This code is used to take care of third level drop-downs in IE for the sons of suckerfish dropdown. Inserts iframes in third levels due to select items having an infinite z-index in IE. The original fix addressed second-level elements.

Based on: http://www.loadedguntheory.com/devblog/director/list/b5349120-f9ca-1027-b38e-00508df3c0f7.html And: http://www.htmldog.com/articles/suckerfish/dropdowns/
