Twitter bootstrap dropdown goes outside the screen

Question

I want to implement twitter bootstrap dropdown menu, here\'s my code:

Answer 1

a solution that does not need modifying the HTML only the CSS is

li.dropdown:last-child .dropdown-menu {
  right: 0;
  left: auto;
}

Its particularly usefull for dynamically generated menus where its not always possible to add the recommended class dropdown-menu-right to the last element
