I\'m using Twitter Bootstrap and some custom css (found here) to have dropdown menus open up on mouseover.
I am using the \"caret\" on a on the root menu items to show
I use these styles to do that (it works without bootstrap as well)
HTML:
CSS:
.caret {
border: 5px solid transparent;
display: inline-block;
width: 0;
height: 0;
opacity: 0.5;
vertical-align: top;
}
.caret.up {
border-bottom: 5px solid;
}
.caret.right {
border-left: 5px solid;
}
.caret.down {
border-top: 5px solid;
}
.caret.left {
border-right: 5px solid;
}
