ok, thanks to this thread Hover dropdown menu on touchscreens
and a little changes (below) I have this workaround now.
<script>
$('.w-dropdown').hover(function(evt) {
evt.preventDefault();
var openClass = 'w--open';
if (evt.type == 'mouseenter') {
$(this).find('.w-dropdown-toggle').addClass(openClass);
$(this).find('.w-dropdown-list').addClass(openClass);
}
else if (evt.type == 'mouseleave') {
$(this).find('.w-dropdown-toggle').removeClass(openClass);
$(this).find('.w-dropdown-list').removeClass(openClass);
}
});
</script>
