Thank you, implementing the changes were no problem!
in fact I do have another question:
it would be great to have a function to hide the list-wrap DIV, to size down the navigation. It tried with another category as a link but the problem is that though I hide the list-wrap DIV the size of the example-one div (the whole navigation) stays the same.
would it be easy to create a category in the navigation bar to hide/unhide the list-wrap with resizing?
thank you for your help!
