Select2 Dependent dropdown lists

Question

I am trying to use the Select2 plugin to have 4 dropdown lists that depend on each other. I have struggled to find the right way to update the data that loads the options in.

Answer 1

Igor has come back to me with a way to do this

var data=[...];    
$().select2({data: function() {return {results:data};}});    
/// later    
data=[...something else];    
// next query select2 will use 'something else' data
