Manage Object Visibility

gistfile1.js

var manageItems = ["l1","l2","l3","l4"];
function showItem(joinToShow) {
	var hideItems = [];
	for (var i = 0; i < manageItems.length; i++) {
		if (manageItems[i] != joinToShow) {
			hideItems.push({join: manageItems[i], opacity: 0});
		}
	}
	hideItems.push({join: joinToShow, opacity: 1});
	CF.setProperties(hideItems);
}

// Then from a button, call something like:
// showItem("l1");
