The Tab container shows the information contained within its children as its own tab. For example, in the Classic View, the Features panel is a Tab container type with multiple widgets that each appear as a separate tabs (Parameters, Connections, State Tables, Display, Advanced, and BACnet Exposed).
The Tab container includes a Position property that determines where the tabs appear within the container. You can position tabs to be on the top, bottom, left, or right of the container. Figure 1 shows the Position property behavior in the UI.
