Select2 is a would-be better-than-before select list in the jQuery space.

This has some notes on it and just as you might otherwise have...

$("#changeme")[0].change(funtion() { ...

 
 

...you may now have...

$("#changeme")[0].select2(funtion() { ...

 
 

...but I'm not yet sure how this is different than the change approach or what the benefit is.
