It's not perfect in meaning of design, but it shows off the concept.

I used jQuery with that.

$(function(){
    var state = 0;
    $('#up').click(function(){
        state += 1;
        $('ul.wrapper').animate({marginTop:(15-state*35)+'px'},400);
    });
    $('#down').click(function(){
        state -= 1;
        $('ul.wrapper').animate({marginTop:(15-state*35)+'px'},400);
    });
});

So, finally I think I have what you are looking for:

Fiddle: http://jsfiddle.net/fzXMg/2/

CSS and HTML is in the Fiddle...

JS:

$(function(){
    var state = 0;
    var maxState = 6;
    var winWidth = $(window).width();
    $(window).resize(function(){
        winWidth = $(window).width();
        $('.box,.container_element').width(winWidth-100);
    }).trigger('resize');
    $('#lefty').click(function(){
        if (state==0) {
           state = maxState;
        } else {
           state--;
        }
        $('.container_element').animate({scrollLeft:((winWidth-100)*state)+'px'}, 800);
    });
    $('#righty').click(function(){
        if (state==maxState) {
           state = 0;
        } else {
           state++;
        }
        $('.container_element').animate({scrollLeft:((winWidth-100)*state)+'px'}, 800);
    });
});

This uses jQuery again.

Now that the healthunit site has changed the original question is not completely clear.

To make a nav menu that scrolls horizontally uses arrow buttons (instead of scrollbar) can be implemented with a little jQuery and easily converted to pure JavaScript.

var $bar = $('.nav');
var $container = $('#outer');
var widths = {};
var scrollOffset = 0;

var container = document.getElementById("outer");
var bar = document.getElementById("bar");

function setMetrics() {
    metrics = {
        bar: bar.scrollWidth||0,
        container: container.clientWidth||0,
        left: parseInt(bar.offsetLeft),
        getHidden() {
            return (this.bar+this.left)-this.container
        }
    }

    updateArrows();
}

function doSlide(direction){
    setMetrics();
    var pos = metrics.left;
    if (direction==="right") {
        amountToScroll = -(Math.abs(pos) + Math.min(metrics.getHidden(), metrics.container));
    }
    else {
        amountToScroll = Math.min(0, (metrics.container + pos));
    }
    $bar.css("left", amountToScroll);
    setTimeout(function(){
        setMetrics();
    },400)
}

function updateArrows() {
    if (metrics.getHidden() === 0) {
        $(".toggleRight").addClass("text-light");
    }
    else {
        $(".toggleRight").removeClass("text-light");
    }

    if (metrics.left === 0) {
        $(".toggleLeft").addClass("text-light");
    }
    else {
        $(".toggleLeft").removeClass("text-light");
    }
}

function adjust(){
    $bar.css("left", 0);
    setMetrics();
}

$(".toggleRight").click(function(){
    doSlide("right");
});

$(".toggleLeft").click(function(){
    doSlide("left");
});

$(window).on("resize",function(){
    // reset to left pos 0 on window resize
    adjust();
});

setMetrics();

Check out this jsfiddle: http://jsfiddle.net/7vvdB/

Basically, create an outer container with a max-width of 100% and a overflow-x:scroll, then create an inner container with a fixed width large enough to fit all of your elements, then put all of your elements in the inner container.

.container_element
{ white-space:nowrap
    min-width:100%;
    overflow-x:scroll;
    overflow-y:hide;

}

.inner_container
{
    width:5000px;
}
}
