I have problem making this plunkr (select2 + angulat-ui) work.

In local setup, I get the select2 work, but I cannot set
Setting width to 'resolve' didn't work for me. Instead, i added "width:100%" to my select, and modified the css like this :
.select2-offscreen {position: fixed !important;}
This was the only solution that worked for me (my version is 2.2.1) Your select will take all the available place, it is better than using
class="input-medium"
from bootstrap, because the select is always staying in the container, even after resizing the window (responsive)
