After click don't scroll to top

Question

I'm really stuck and although i found some tips and tricks (javascript) i don't get it t work. Problem is i have a great looking and functioning collapseble menu but when i click on the main links (Nederland, Belgie, Frankrijk, Zoeken) the page scrolls to top.

I rather not fix this with javascript onclick because i would like to keep the "href" links intact because of SEO purposes.

I hope you guys and girls can help me out, would be much appreciated!

    <ul class="mainMenuA">
        <li class="item" id="nl">
            <a href="#nl" class="btnA"><span class="flag flag-nl"></span> Nederland</a>
            <div class="subMenu">
                <a href="/amsterdam">Amsterdam</a>
                <a href="/arnhem">Arnhem</a>
                <a href="/utrecht">Utrecht</a>
            </div>
        </li>
        <li class="item" id="be">
            <a href="#be" class="btnA"><span class="flag flag-be"></span> België</a>
            <div class="subMenu">
                <a href="/item1">item-1</a>
                <a href="/item2">item-2</a>
            </div>
        </li>
        <li class="item" id="fr">
