The scroll spy now seems a nested scroll spy it can only spy the scroll nested in a page. The spied content is defined like this<div class="scrollspy-example z-depth-1 mt-4" data-spy="scroll" data-target="#navbar-example2" data-offset="0">If I remove the "scrollspy-example" the content become whole page content. And the scrollspy not work again.So how to make global scrollspy.
