问题
I'm having trouble with css, revealing more than two sub-cateogories under menu header. Please take a look at example here http://thebrlab.com/ugo-mozie/
回答1:
Line 33 in your stylesheet - menu.css.
Change the height on :hover from 93px to 155px;.
.menu-item:hover ul {
height: 155px;
}
Pretty self explanatory.
