How to make the mega menu longer ?

I am using Gavick Template Mucity . I want to make the mega menu longer than default, i found it in mega.css and gk_stuff.css but i don't know what value ? Can you help me ?
Thanks advance

Find file /templates/gk_musicity/css/gk_stuff.css and change rule:
#gk-nav ul.level0 > li a {
color: #9F9F9F;
display: block;
font-size: 17px;
height: 28px; // set height:auto or just remove height property
line-height: 28px;
padding: 0 20px;
}

Thanks Krzysztof Malina:kiss: . I deleted height property and the mega menu is shown full character. But i want it show full character in 1 line ? Can you help me
