This example shows how to use the CesiumExt.data.store.ImageryLayerTreeStore with an editable Tree Grid Panel:

• Each Change in the Tree Grid Panel will be reflected in Cesium.ImageryLayer
• Drag&Drop is available to move the ImageryLayer position

Remark: Double click in the Tree Grid Row to edit the Cesium ImageryLayer properties.

Have a look at imageryLayerTreeGrid.js to see how this is done.
