问题
Here is the link on jsfiddle with some demo. It works well in Chrome and even in IE, but in FF icons get down. How can I fix it without moving them up with negative margins or something like this? I have no ideas why this happens.
回答1:
Just add the following style
.dropdown-menu a {
white-space:normal;
}
DEMO.
