Insert scroll button horizontal using jQuery

Issue

I am trying to replicate this example into my own coding.

The List tabs are generated dynamically using JS and each have their table (also generated using JS). Unfortunately, there is a problem where the button won't show even after resizing the screen. I couldn't find anything that I missed out though.

And another problem is that when reload, sometimes there is an error at line $('.nav-item').last().offset().left eventhough I already load the reAdjust() function in $( document ).ready(function().

Solution

I found the issue where there are other classes with the same name list which is why the button won't show up properly.
