I have got a vertical menu on the left side of the screen, and i want to take 100% height of the resolution, but if the div(of the menu) needs more, i want to appear scroll. My question: I have got one div with height:100% and overflow auto. I need have the scroll only on that div, but this div must be 100% of the resolution of the screen. Now if i put like this, the scroll takes all the page, but if i put fixed height to the div it works correctly. But i need to be 100% height. Thank you very much!
