responsive menu – adjust height

Hi!
first of all, your plugin is totally awesome!!!
I have a similar problem,i dont wont that after the last menu link the menu extends empty until the bottom of the site…the responsive menu box should have just the height the links/sublinks require… and tried the same solution as above, but it does not work…my site is http://www.betriebsblind.at

can you help me please?

Thanks and greets from vienna!
