drupal bootstrap theme working with superfish
Superfish allows you to add custom css classes to the menu items. If you prefer to do it that way 



you might want to first select the classes from bootstrap that you want to use to style your superfish menu items. Second add those classes correspondingly in the superfish menu block settings(click configure next to the block). 

I also added a html wrapper under advanced HTML settings around the main UL element which is simply , (comma denotes the beginning and ending wrapping elements).

Let me know if that helps!
