bootstrap dropdown bubble align right (not push-right)

<div class="dropdown-menu dropdown-menu-right">

This is still working in boostrap 4.2.1 :)

This can be solved with the bootstrap class dropdown-menu-right with dropdown-menu that is specifically for this problem that uses the css properties right: 0; and left: auto; to right align it.

This solution is working for me.

Bootstrap 5+ (Update June 2022)

dropdown-menu-right has been replaced with dropdown-menu-end

<div class="dropdown-menu dropdown-menu-end">
    STUFF
</div>

Bootstrap 3.1+

Adding the class .dropdown-menu-right to the same div containing the class dropdown-menu:

<div class="dropdown-menu dropdown-menu-right">
    STUFF
</div>

Bootstrap 2.3 & 3.0

Add the class .pull-right to the same div containing the class dropdown-menu

<div class="dropdown-menu pull-right">
    STUFF
</div>

This seems to work for me using bootstrap 3.0
