li.each(function (i) {
$(this).css("z-index", count - i);
});
function setClosed() {
li.each(function (index) {
$(this).css("top", index * 4).css("width", width - index * 0.5 + "%").css("margin-left", index * 0.25 + "%");
});
li.addClass("closed");
toggler.removeClass("active");
}
setClosed();
toggler.on("mousedown", function () {

setClosed();
} else {
$this.addClass("active");

li.each(function (index) {
$(this).css("top", 60 * (index + 1)).css("width", "100%").css("margin-left", "0px");
});
}
});
links.on("click", function (e) {
var $this = $(this), label = $this.data("label");
