I would really like to change the look of the select2 element. My other elements use the following bootstrap classes: form-control & form-control-sm.
I am using the bootstrap theme for select2 but using those classes does not change the look of the select2 element. I used input-sm which gets it close but it is a few pixels out and the boarder is very slightly different.
I suspect this might be because the theme only supports bootstrap 3 and form-control-sm is from bootstrap 4?
Is there anything I can do?
