Dear kpanchoo,
You open the file of templates/ja_community_plus/css/menu/mega.css and try as following
1) For active,Look for this css
.ja-megamenu ul.level0 li.mega a.mega.active {
background: url(“../../images/grad-01.png”) repeat-x scroll left top transparent;
border: 0 none;
color: #FBCC93;
margin: 0;
padding: 15px 20px;
}
You can change the color and the background color as well here.
2)For hover,Look for this css
.ja-megamenu ul.level0 li.mega a.mega.over {
background: url(“../../images/grad-03.gif”) repeat-x scroll left bottom transparent;
border-color: #938781 #938781 -moz-use-text-color;
border-style: solid solid none;
border-width: 1px 1px 0;
margin: 0 -1px;
padding-top: 14px;
}
And also make changes as you want.
