Bootstrap - scrollspy responsivness not working
I have problem with responsivness of the page. If I go to half width of the page, the scrollspy disapear. I have no idea why.
You can see whole page if you run code I posted here.
I have another page that has not problem with responsivnes, there I do not use scrollspy.
I would like to give you more information, but I've used Bootstrap 3x and now I am doing just a school project.

You can't see the whole page because at some point (on the div you want to see) you have .d-none .d-xl-block , this will let visible the div with these classes only on xl screen devices
So you should remove these and it would become:
<div class="col-xl-2 bd-toc disapear1">
Will share the full code just with that little correction, you also forgot to close the inline-style on the div in the footer (fixed as well) here you are:

p.s. i saw that now the first section is hidden by the navbar, you should set a margin-top to avoid that
