I applied word-wrap: break-word to twitter bootstrap dropdown-nemu, but it didn\'t work. Here\'s the JSFiddle.
I tried a simplified sample and it worked:
It was because of white-space: nowrap property with link.. add this line:
- sometextsometextsometextsometextsometext
..or use full fiddle here: http://jsfiddle.net/Ex5fA/45/ (you had also typos with your .dropdown-menu selector.. it was typed .dorpdown-nenu ;)
