How to implement select2 with lock selection?

Question

I am trying to use select2 with one disabled value.

I am trying to implement it like

$('#select_currency').select2('data', preloaded_data);

I have been reading about Lock selections but I am not able to implement it, could you please someone let me know how to implement it or is there any tutorial about it.

You can easely add locked="locked" if you use v3.5 http://select2.github.io/select2/#locked-selections.

But in v.4.x this functionality is removed.

I've found solution (or hack:) ) for v.4.x, a little bit dirty with error in console, but it works. Anyway it is best solution what I've found. Check my jsfiddle:
