HTML CSS LI Wrapping

Answer 1

Use white-space:nowrap. Like so:

li {
  white-space:nowrap;
}

Here's some documentation.

Answer 2

ul {
  overflow: auto;  // allow li's to overflow w/ scroll bar
                   // at the bottom of the menu
}

li {
  white-space: nowrap; // stop the wrapping in the first place
}

You would also need to give the style the ul:

ul{
 width:250px;
 overflow:auto;
}
