Usage​

groupBy?: string | {
  field: string,
  taskHierarchy?: boolean,
  resourceHierarchy?: boolean,
  multipleResources?: boolean,
  ungrouped?: false | "top" | "bottom",
  resolver?: (task: ITask) => any,
};

Parameters​

  • field - (required) the field to group tasks by; use "resource" to group by assigned resources, or any task field name (e.g., "status", "priority")
  • taskHierarchy - (optional) if true, preserves the task parent/child structure within each group; Default: false
  • resourceHierarchy - (optional) if true, shows the resource hierarchy (teams and people) within resource groups; applies only when field is "resource"; Default: true
