Thanks again,
It was my mistake, corrected and now works.
I have another quick question (hopefully the last one). I want to do some extra styling to achieve something like here https://www.sparkfun.com/ . With their vertical menu when hover over the ‘+’ sign (see the right to Arduino item) it changes color, while hover over menu item changes color for that item plus the ‘+’ sign. Can I do it with css and if yes what is the class selector for corresponding items in your Bootstrap add-on menus? Or should I modify the .Hover function in js?
Cheers,
Jan
