Item ordering

+

+ By default, the items displayed on the Timeline are unordered. They are + stacked in the order that they where loaded. This means that way items are + stacked can change while moving and zooming the Timeline. +

+

+ To display and stack the items in a controlled order, you can provide a + custom sorting function via the configuration option order. + This is only suitable for relatively small amounts of items, as it forces + the Timeline to order and re-stack all items with every redraw. +
