Hello! Looks like a simple fix, should not take more than an hour. i'll need access to your ftp. Your site looks like in opencart, if it is and the theme is free I can do it without getting into your system . I shall modify and give you the file and you'll replace it.
I have been working in web development for 2years now and I know these jquery, bootstrap functions quite well. I am available over chat!
Thanks!
