I have a written a jquery plug-in which pops-up a div section on hover over an element, and I need to deal with the "select z-index" bug in IE6 (http://blogs.msdn.com/ie/archive/2006/01/17/514076.aspx). So, if running in IE6, my code needs to hide some select boxes on the page, when the pop-up div is visible.
My question is: In trying to follow best practices, I would like to avoid detecting the actual browser version and instead do a 'feature-test", to determine whether I am in an affected browser. (http://ejohn.org/blog/future-proofing-javascript-libraries). Is there any way to do this? Or should I just treat this as a special case, detect the browser and handle IE6?
