Thanks for your time,
I did manage to do what I want with these lines of code in a js snippet:
$( ".ButtonNextPage" ).click(function() {
document.getElementsByClassName("mx-name-container1")[0].scrollIntoView();
});
that scroll to the top just before the page is changing, that the only solution that worked properly for me.
Add a html/javascript widget to the page with a small piece of javascript:
<script>
$(document).ready(function(){
$(window).scrollTop(0);
});
</script>
Think Erwin's solution will work. But do you mean that you are on a page which is scrolled to the bottom, then click a button which opens a new page and the new page is also scrolled to the bottom? If so, this is not normal behavior. The new page should be automatically scrolled to the top.
