Parent Resources

The resources (rows) with child nodes have special behavior.

• You can prevent the parent resources from being used for scheduling.

• You can highlight the parents using CSS. The parent node cells are marked with *_cellparent class (CssOnly mode).

• You can load the children dynamically.

JavaScript

<div id="scheduler"></div>
<script>
  const scheduler = new DayPilot.Scheduler("scheduler", {
    treePreventParentUsage: true,
    // ...
  });
  scheduler.init();
</script>

API: treeEnabled, treePreventParentUsage.

In the examples, Rooms is a category node and Room A and Room B remain bookable children. treePreventParentUsage prevents scheduling in the parent row.

The framework examples use DayPilot Pro. For installation, see the Angular, React or Vue Scheduler guide.

Angular

import {Component} from "@angular/core";
import {DayPilot, DayPilotModule} from "daypilot-pro-angular";

@Component({
  selector: "app-scheduler-example",
  standalone: true,
  imports: [DayPilotModule],
  template: `
    
    <daypilot-scheduler [config]="config"></daypilot-scheduler>
  `
})
export class SchedulerExampleComponent {
  config: DayPilot.SchedulerConfig = {
    startDate: "2026-11-01",
    days: 30,
    scale: "Day",
    timeHeaders: [{groupBy: "Month"}, {groupBy: "Day", format: "d"}],
    resources: [{id: "G", name: "Rooms", expanded: true, children: [{id: "A", name: "Room A"}, {id: "B", name: "Room B"}]}],
    events: [{id: 1, text: "Planning", resource: "A", start: "2026-11-03", end: "2026-11-06"}, {id: 2, text: "Delivery", resource: "B", start: "2026-11-08", end: "2026-11-11"}],
    treeEnabled: true,
    treePreventParentUsage: true
  };

}

React

import React from "react";
import {DayPilot, DayPilotScheduler} from "daypilot-pro-react";

export default function SchedulerExample() {

  return <div>

    <DayPilotScheduler
      startDate={"2026-11-01"}
      days={30}
      scale={"Day"}
      timeHeaders={[{groupBy: "Month"}, {groupBy: "Day", format: "d"}]}
      resources={[{id: "G", name: "Rooms", expanded: true, children: [{id: "A", name: "Room A"}, {id: "B", name: "Room B"}]}]}
      events={[{id: 1, text: "Planning", resource: "A", start: "2026-11-03", end: "2026-11-06"}, {id: 2, text: "Delivery", resource: "B", start: "2026-11-08", end: "2026-11-11"}]}
      treeEnabled={true}
      treePreventParentUsage={true}
    />
  </div>;
}

Vue

const treeEnabled = true;
const treePreventParentUsage = true;

</script>
