zIndex determines the z-order of the widget. With overlapping widgets, the zIndex determines which widget is on the top and which one is on the bottom. The widget with the larger zIndex is on top, and the one with the smaller zIndex is on the bottom. The zIndex must be unique within a piece of content or a container widget. The zIndex is automatically assigned by the visual editor and can therefore be changed via the toolbar. |
