I have adapted a css accordian menu so that it also contains sub menus in the sliding section. Is there a way to adjust some of the sliding sections so that they don't open? The code for opening the sliding section is;

#accordion div:hover {
	height: 280px; 
The home button slider doesn't have any content in the slider. I want to remove it or to reduce the size to 0px. You can see what I mean here
