If you'd actually bothered to read the existing solution, you'd see that the "refresh" command is for a different plugin than the one the OP is using.

You'd also see that this question has already been solved.

Solution 1

You are doing a "refresh" command at the end. This won't work because "refresh" is a command in this multiselect plugin[^], but you are using a different one[^]. The fix is simple: instead of "refresh", use "reload":

JavaScript

$("#PID").multiselect('reload');

I don't have a lot of experience with the multiselect tool, but there appears to be an 'onOptionClick' event. See the link to the GitHub repository I provided.
