Highligh 2nd level menu when hovered over 3rd level

Hi, I added third level menu to my main-menu according to this this tutorial.
Example menu:

So when hover over category1, subcategories are shown.
What I want to achieve is that when hoverd over any subcategory, that I will still have the main category highligted, so the customer knows which category is he browsing.
Also when already subcategory is clicked and products are being shown and he goes again to navigation that according category and subcategory are still highligted.

Thanks for any advice.
