Multiple Select – Select2 Plugin (jQuery) AJAX

Hi!

I must create form with selectable two options inside SELECT.
It’s possible to do this with AJAX “Ultimate WP Query Search Filter” ?

Plugin who I must use is here:

[code]https://select2.github.io/examples.html [/code]

(Multiple select boxes)

Thanks for any response!
