How would I limit the selection to just one value?
I've tried pattern_options'maximumSelectionLength': 1 and 'selectionAdapter': 'SingleSelection' as widget directive, but no success. (and yes, the options are visible in data-pat-select2)
To answer the question myself: it might not have worked for @agitator right away because the 'adapter' name has changed in select2 4, but we are probably still using select2 < 4 in mockup:
