Bootstrap vertical scrolling tabs-Twitter bootstrap

So I have the following code (which you can see below):

JavaScript:

var hidWidth;
var scrollBarWidths = 40;

var widthOfList = function(){
    var itemsWidth = 0;
    $('.list li').each(function(){
        var itemWidth = $(this).outerWidth();
        itemsWidth+=itemWidth;
    });
    return itemsWidth;
};

var widthOfHidden = function(){
    return (($('.wrapper').outerWidth())-widthOfList()-getLeftPosi())-scrollBarWidths;
};

var getLeftPosi = function(){
    return $('.list').position().left;
};

var reAdjust = function(){
    if (($('.wrapper').outerWidth()) < widthOfList()) {
        $('.scroller-right').show();
    }
    else {
        $('.scroller-right').hide();
    }

    if (getLeftPosi()<0){
        $('.scroller-left').show();
    }
    else {
        $('.item').animate({left:"-="+getLeftPosi()+"px"},'slow');
        $('.scroller-left').hide();
    }
}

reAdjust();

$(window).on('resize',function(e)
{  
    reAdjust();
});

$('.scroller-right').click(function()
{
    $('.scroller-left').fadeIn('slow');
    $('.scroller-right').fadeOut('slow');

    $('.list').animate({left:"+="+widthOfHidden()+"px"},'slow',function(){

    });
});

$('.scroller-left').click(function()
{
    $('.scroller-right').fadeIn('slow');
    $('.scroller-left').fadeOut('slow');

    $('.list').animate({left:"-="+getLeftPosi()+"px"},'slow',function(){

    });
});

CSS:

.wrapper {
    position:relative;
    margin:0 auto;
    overflow:hidden;
    padding:5px;
    height:50px;
}

.list {
    position:absolute;
    left:0px;
    top:0px;
    min-width:3000px;
    margin-left:12px;
    margin-top:0px;
}

.list li{
    display:table-cell;
    position:relative;
    text-align:center;
    cursor:grab;
    cursor:-webkit-grab;
    color:#efefef;
    vertical-align:middle;
}

.scroller {
    text-align:center;
    cursor:pointer;
    display:none;
    padding:7px;
    padding-top:11px;
    white-space:no-wrap;
    vertical-align:middle;
    background-color:#fff;
}

.scroller-right{
    float:right;
}

.scroller-left {
    float:left;
}

The code above creates a horizontal menu which works well. The menu has arrows to scroll horizontally.

So there are these following questions – How to do it:

• I would like to turn them into vertical ones (-> 150px high).

• I need to replace this menu with a vertical one. The items in the menu are to go from top to bottom. The menu is to have a height of 150px.
