    Well I'd say your problem is an inability to "keep it in your pants" when it comes to these derpy garbage frameworks, since I'd sooner suck the business end of a high velocity chemical propelled lead pellet projector than have that many separate scripts and stylesheets. That's what, 8 to 20 seconds of first-load overhead alone? And that's BEFORE we talk their being blocking scripts due to being placed in HEAD, the decade out of date attributes, the X-UA rubbish that's an indicator the markup AND scripting is garbage...

    Yet even with all this, you've not shown any code that ACTUALLY seems to be your problem.

    Honestly, it looks like you need to deep six the entire site and start over from scratch, but that's a common problem when you use the "Monuments to developer ignorance, incompetence, and ineptitude that are HTML / CSS / JS frameworks". I'd link to my article on that, but Xenforo's dipshit post/link parser is shite.

    I shudder to think what a walking-talking WCAG violation that site is with the derpy jQuery UI bull and infragristics crap telling users with accessibility needs to go plow themselves. Hope that's not for a real business since it's now open season on inaccessible websites..

    As to your immediate problem, I'd have to see the real site live to even try to figure out where that's going wrong... though really, just put it down like Old Yeller and start over without the bloated framework idiocy.
