Facing focus issue while click the select2 element

I have three select2 element in my single page like below, (Select2 version V4.0.0)


While I am click the first select2 element the focus automatically moved to final select2 element.

Version 4.0.0 is fairly old. You should upgrade to the latest version. If that doesn’t resolve your problem, then I would need to see your actual code to troubleshoot the issue further.
