I try many solution from stackoverflow, but none seem to work. I can do this ?

    <div class="col-sm-12">
        <div id="panel-profil" class="panel panel-info">
            <div id="panel-heading-profil" class="panel-heading text-center">
                <a id="link-heading-profil" role="button" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo"
                   aria-expanded="false" aria-controls="collapseTwo" onclick="changeArrowProfil()">
                    <div class="row">
                        <div id="triangleUn" class="col-sm-1">

Answer 1

If your using an onClick event, then within that onClick, write this line of code,

window.scrollTo(0,document.body.scrollHeight);

This will scroll you to the bottom of the page.
