Is there any more complexity to add multiple option in select in your plugin? You have everything except this option in your plugin.
I cant use checkboxes as it will occupy more space and not user friendly. Other side I am using select2 to provide good UI for the user hence single selection is not useful for me. If you do not wish to include in your stable plugin but if there is any way/option available, kindly suggest. I can do it on our installation to full-fill our requirements.
Thanks
