JS tabs - show content only after mouse hover

JS tabs - show content only after mouse hover

I am looking for some solution for this: I need something like this:
http://jqueryui.com/tabs/#mouseover But with some default content block
(without tab mennu item) and show other items only which mouseover is on
some item. When cursor is gone from item then show default block again.
Basically same effect like this: http://jsfiddle.net/RM3yr/2/
I can not JS, so I m looking for ready-made solution.
Thanks a lot
