FREE SCROLLABLE THUMBS MENU WITH JQUERY




VIDEO DEMO                        DOWNLOAD

Hi dear visitors , to day im going to share awesome image menu for website that is free.In this tutorial we will create a fixed menu with scrollable thumbs. The idea is to have a menu fixed to the bottom of the page and let a vertical stack of thumbs appear when hovering over a menu item. The thumbs are scrollable by moving the mouse up and down which makes a really nice effect. We will add some CSS3 properties for spicing up the looks.
We will base our jQuery code on the Vertical Scrolling Menu of Andrew Valums.
The images used in the demo are from the incredible fashion photo collection by kk+ on flickr.
So let’s get started!

THE MARKUP

The HTML is pretty straightforward. We have an unordered list with a link element and wrapper div that contains the menu with the thumbs:
1
2
3
4
5
6
7
8
9
10
11
12
13
<ul class="menu" id="menu">
    <li>
        <a href="#">Brand 1</a>
        <div class="sc_menu_wrapper">
            <div class="sc_menu">
                <a href=""><img src="images/1.jpg" alt=""/></a>
                <a href=""><img src="images/2.jpg" alt=""/></a>
                ...
            </div>
        </div>
    </li>
    ...
</ul>
I just show an excerpt here, since it already outlines how to build the structure.
Let’s have a look at the style.

THE CSS

First, we will set that any overflow of the body will not show any scrollbars:
1
2
3
body{
    overflow:hidden;
}
This is not really necessary for this to work but it just looks very nice and if there is not much else in the page, it is not really problematic.

/* Navigation Style */
ul.menu{
    list-style:none;
    font-family: "Trebuchet MS", Arial, sans-serif;;
    font-size: 15px;
    font-style: normal;
    font-weight: normal;
    text-transform:uppercase;
    letter-spacing: normal;
    line-height: 1.45em;
    position: fixed;
    bottom:0px;
    left:0px;
    width:700px;
    height:100%;
}
If you want your page to be scrollable, then make sure to set the menu fixed, if you want it to stick to the bottom of the page. The list elements and the links will be styled as follows:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22

24

26
ul.menu li{
    float:left;
    position:relative;
    height:100%;
    width:130px;
}
ul.menu li > a{
    position:absolute;
    bottom:0px;
    left:0px;
    width:130px;
    height:40px;
    text-align:center;
    line-height:40px;
    color:#ddd;
    background-color:#291A2F;
    letter-spacing:1px;
    cursor:pointer;
    text-decoration:none;
    text-shadow:0px 0px 1px #fff;
    -moz-box-shadow:-1px 0px 5px #000;
    -webkit-box-shadow:-1px 0px 5px #000;
    box-shadow:-1px 0px 5px #000;
    opacity:0.9;
    filter:progid:DXImageTransform.Microsoft.Alpha(opacity=90);
}
OK, before people start ranting now, no, we don’t need a link element, we might as well use a span or whatever. I am just so traditional. I will start using non-link elements next time :)
With a white text shadow behind a white text, we get a slight blur of the font which gives a smooth effect (especially in Chrome). That last ugly line is the opacity filter for IE.
Be careful using that crappy filter on png images that have some (semi-)transparent parts: IE fills it out with charming BLACK.
The style for the thumb menu wrappers will look as follows:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
/* Thumb Scrolling Style */
div.sc_menu_wrapper {
    position: absolute;
    top:0px;
    width:150px;
    overflow: hidden;
    bottom:0px;
    left:0px;
    visibility:hidden;
}
div.sc_menu {
    width:130px;
    visibility:hidden;
}
Now, why do we use visibility:hidden here? We have two reasons: one is that we want to make the thumbs appear as if we stack them from bottom to top, so we already “place” the elements there and then just set them visible (see in the JS). With display:none, you actually make the element not taking any width or height in the page, but with visibility:hidden we still occupy the space, the element is just not “visible”.
The reason why we do that to the wrappers is because of the scrolling function in jQuery that gets the height of the elements. If our element is not displayed, that’s not really possible. Visibility solved that issue.
The thumb links and the thumb images are styled as follows:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
.sc_menu a {
    display: block;
    background-color:#22002F;
    color: #fff;
    text-align:center;
    -moz-box-shadow:3px -3px 3px #3B0F4F;
    box-shadow:3px -3px 3px #3B0F4F;
    -webkit-box-shadow:3px -3px 3px #3B0F4F;
}
.sc_menu img {
    display: block;
    border: none;
    opacity:0.3;
    filter:progid:DXImageTransform.Microsoft.Alpha(opacity=30);
}
That was the style and now, let’s add some magic!

THE JAVASCRIPT

The main idea is to build the thumbs menu when we hover over the main navigation items. We show the thumbs in a stacking order, one after the other, with a time delay (line 34-44).
The “buildThumbs” function will let us scroll through the thumbs without a scroll bar, by moving the mouse to the top or to the bottom.
The “inactiveMargin” let’s us reach the topmost and the bottommost thumbs better, so that we can actually see the images entirely and not cut off.
Initially, we want to start at the bottom, so we scroll down (line 13).
When we leave the main list items, we put everything back to normal, we hide everything again (line 49-58).
When we hover over the thumbnails, we will change the opacity (line 62-75)

            --pos;
        };
 
        /* each thumb will appear with a delay*/
 
        stacktime = setInterval(f , 50);
    });
 
    /* on mouseleave of the whole <li> the scrollable area is hidden */
 
    $('#menu li').bind('mouseleave',function () {
        var $this = $(this);
        clearTimeout(stacktime);
        $this.find('.sc_menu')
             .css('visibility','hidden')
             .find('a')
             .css('visibility','hidden');
        $this.find('.sc_menu_wrapper')
             .css('visibility','hidden');
    });
 
    /* when hovering a thumb, change its opacity */
 
    $('.sc_menu a').hover(
        function () {
            var $this = $(this);
            $this.find('img')
            .stop()
            .animate({'opacity':'1.0'},400);
        },
        function () {
            var $this = $(this);
            $this.find('img')
            .stop()
            .animate({'opacity':'0.3'},400);
        }
    );
});
And that’s it! Enjoy!
