carouFredSel: Show partial items?

Question

I'm using carouFredSel to create a vertical carousel. Everything works great, except I would prefer if partial items would be shown at the bottom, cropped, rather than being hidden. This way it would indicate to users that there are additional items that can be scrolled.

I have been reading the documentation, but so far can't tell if what I am after is possible.

Check out the JSFiddle to see what I mean. Watch the bottom most item on the page.

Javascript

$("ul").carouFredSel({
    direction: "up",
    align: "top",
    width: 100,
    height: "100%",
    items: {
        visible: "variable",
        width: 100,
        height: "variable"
    },
    scroll: {
        items: 1,
        mousewheel: true,
        easing: "swing",
        duration: 500
    },
    auto: false,
    prev: {
        button: ".prev",
        key: "up"
    },
    next: {
        button: ".next",
        key: "down"
    }
});​

Answer 1

This is a bit of a hack, but it works. Set the height of the scroller (in this case, ul) to 150% and the parent element (in this case, body) to overflow: hidden. Now the bottom most element is off screen.

Javascript

$("ul").carouFredSel({
    height: "150%"
});

CSS

body {
    overflow: hidden;
    }

The next not visible element in the vertical carousel is pushed down by the margin. I'm currently overriding it by the following function:

function cropCarousel () {
    var visibleElements = this.triggerHandler("currentVisible"), // show all visible
    $lastElement = $(visibleElements[visibleElements.length - 1]); // get the last one

    $lastElement.css('margin-bottom', '30px'); // amend the margin
};

cropCarousel.call($('#your_carousel_id'));

The downside of it that you will have to call this function on carousel init and on up and down events. But it works ;)

Ha, caroufredsel supports it, no hacks required :))! You can achieve it with the following option:

items: {
    visible: '+1'
}

EDIT: This suffers from a problem though. If number of whole visible items + 1 == number of all items, then carousel cannot be scrolled even though one image is visible just partially. You can overcome this issue by setting e.g. minimum: 1 but it is not always a way to go (e.g. if number of images is dynamic and you don't want scroll handlers to appear when there is just one or two images.).
