bootstrap dropdown bubble align right (not push-right)

Question

Bootstrap 5+ (Update June 2022)

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

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

https://getbootstrap.com/docs/5.2/components/dropdowns/#menu-alignment

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
