In the timeline view, each row depicts a single resource, whereas in vertical views, each resource is grouped parallelly as columns. Here, the resource grouping follows the tree-view like hierarchical grouping structure and can contain any level of child resources. They are grouped in layout by using the ScheduleGroup property and its order of grouping depends on the order of names passed onto the Resources option within ScheduleGroup.

Also, the colors defined for the child level resources will be applied to the events of those resources by default. In case, if the colors of parent level need to be applied to those child events, then it is necessary to define the ResourceColorField option within the ScheduleEventSettings property with the parent level resource name value.
