    </div>
</main>
<footer class="container-fluid">my footer here</footer>
</body>

解决方案

I had same problem (jump to the top on click to the link which was triggering the collapse toggle) the href="#" was changed to href="javascript:void(0);" and it is working great (toggling collapse without any scrolling to the top)
