claudes,
I recently modified the jCarouselLite plugin to take in a
parameter for how many rows that you want shown when scrolling
horizontal or columns when scrolling vertical. I am not sure the
easiest way to get you the code so I am just going to paste it here.
(function($) { // Compliant
with jquery.noConflict()
$.fn.jCarouselLite = function(o) {
o = $.extend({
btnPrev: null,
btnNext: null,
btnGo: null,
mouseWheel: false,
auto: null,
speed: 200,
easing: null,
vertical: false,
circular: true,
visible: 3,
start: 0,
scroll: 1,
rows: 1, //ADDED: Property to allow multiple rows
beforeStart: null,
afterEnd: null
}, o || {});
return this.each(function() { //
Returns the element collection. Chainable.
var running = false, animCss = o.vertical ? "top" :
"left", sizeCss = o.vertical ? "height" : "width";
var div = $(this), ul = $("ul", div), tLi = $("li", ul),
tl = tLi.size(), v = o.visible;
var rowCss = o.vertical ? "width" : "height"; //ADDED:
rowCss is used to set the height/width of the viewport based on how
many rows are showing
if (o.circular) {
ul.prepend(tLi.slice(tl - v - 1 + 1).clone())
.append(tLi.slice(0, v).clone());
o.start += v;
}
var li = $("li", ul), itemLength = li.size(), curr =
o.start;
div.css("visibility", "visible");
li.css({ overflow: "hidden", float: o.vertical ? "none" :
"left" });
ul.css({ margin: "0", padding: "0", position: "relative",
"list-style-type": "none", "z-index": "1" });
div.css({ overflow: "hidden", position: "relative", "z-
index": "2", left: "0px" });
var liSize = o.vertical ? height(li) : width(li); //
Full li size(incl margin)-Used for animation
var liRowSize = o.vertical ? width(li) : height(li); //
ADDED: size of the li's row
var ulSize = ((liSize * itemLength) / o.rows) + (liSize /
1.5); // size of full ul(total length, not just for
the visible items)
var divSize = liSize * v; // size
of entire div(total length for just the visible items)
var rowSize = liRowSize * o.rows; //ADDED: gets the size
in pixels of the height/width of the viewport
li.css({ width: li.width(), height: li.height() });
ul.css(sizeCss, ulSize + "px").css(animCss, -(curr *
liSize));
div.css(sizeCss, divSize + "px"); //
Width of the DIV. length of visible images
div.css(rowCss, rowSize + "px"); //
ADDED: Height of the DIV
//ADDED: special consideration for vertical carousels with
multiple rows
if (o.vertical && o.rows > 1) {
ul.children().filter(function(index) {
return ((index + 1) % o.rows > 0);
}).css({ float: "left", width: "" });
}
if (o.btnPrev)
$(o.btnPrev).click(function() {
return go(curr - (o.scroll));
});
if (o.btnNext)
$(o.btnNext).click(function() {
return go(curr + (o.scroll));
});
if (o.btnGo)
$.each(o.btnGo, function(i, val) {
$(val).click(function() {
return go(o.circular ? o.visible + i : i);
});
});
if (o.mouseWheel && div.mousewheel)
div.mousewheel(function(e, d) {
return d > 0 ? go(curr - o.scroll) : go(curr +
o.scroll);
});
if (o.auto)
setInterval(function() {
go(curr + o.scroll);
}, o.auto + o.speed);
function vis() {
return li.slice(curr).slice(0, v);
};
function go(to) {
if (!running) {
if (o.beforeStart)
o.beforeStart.call(this, vis());
if (o.circular) { // If circular we are
in first or last, then goto the other end
if (to <= o.start - v - 1) { // If
first, then goto last
ul.css(animCss, -((itemLength - (v * 2)) *
liSize) + "px");
// If "scroll" > 1, then the "to" might
not be equal to the condition; it can be lesser depending on the
number of elements.
curr = to == o.start - v - 1 ? itemLength
- (v * 2) - 1 : itemLength - (v * 2) - o.scroll;
} else if (to >= itemLength - v + 1) { // If
last, then goto first
ul.css(animCss, -((v) * liSize) + "px");
// If "scroll" > 1, then the "to" might
not be equal to the condition; it can be greater depending on the
number of elements.
curr = to == itemLength - v + 1 ? v + 1 :
v + o.scroll;
} else curr = to;
} else { // If non-circular and
to points to first or last, we just return.
//ADDED: This determines when to stop
scrolling when more than 1 row is viewable
if (to < 0 || to > ((itemLength - v) /
o.rows)) return;
else curr = to;
} // If neither
overrides it, the curr will still be "to" and we can proceed.
running = true;
ul.animate(
animCss == "left" ? { left: -(curr * liSize)} :
{ top: -(curr * liSize) }, o.speed, o.easing,
function() {
if (o.afterEnd)
o.afterEnd.call(this, vis());
running = false;
}
);
// Disable buttons when the carousel reaches the
last/first, and enable when not
if (!o.circular) {
$(o.btnPrev + "," +
o.btnNext).removeClass("disabled");
//ADDED: This determines when to add the
disabled class to the link when more than 1 row is viewable
$((curr - o.scroll < 0 && o.btnPrev)
||
(curr + o.scroll > ((itemLength - v) /
o.rows) && o.btnNext)
||
[]
).addClass("disabled");
}
}
return false;
};
});
};
function css(el, prop) {
return parseInt($.css(el[0], prop)) || 0;
};
function width(el) {
return el[0].offsetWidth + css(el, 'marginLeft') + css(el,
'marginRight');
};
function height(el) {
return el[0].offsetHeight + css(el, 'marginTop') + css(el,
'marginBottom');
};
})(jQuery);
I added comments starting with "ADDED" above or on the lines that I
editted or added. Based on the first image in your post, try
declaring the carousel like this:
markup:
<div class="CLASSNAME">
<ol>
<li>CONTENT</li>
<li>CONTENT</li>
<li>CONTENT</li>
</ol>
</div>
javascript:
$(document).ready(function(){
$(".CLASSNAME").jCarouselLite({
vertical: true,
scroll: 3,
visible: 3,
rows: 2
});
});
Let me know how that works out for you.
