This type of layer provides a way to group other layers together. Having a group layer allows to set common options like visibility or opacity, to all child layers at once.
If data property is configured for a group layer, this data is applied to all custom child layers. This enables multiple layers to share the same data while allowing for different drawing configurations, such as using different symbols for the same feature.
The following table provides the specific configurable options available for this layer:
