Group in React Diagram component

5 Feb 202524 minutes to read

Create group

Group is used to cluster multiple nodes and connectors into a single element. It acts like a container for its children (nodes, groups, and connectors). Every change made to the group also affects the children. Child elements can be edited individually.

Add group when initializing diagram

A group can be added to the diagram model through nodes collection. To define an object as group, add the child objects to the children collection of the group. The following code illustrates how to create a group node.

  • While creating group, its child node need to be declared before the group declaration.

Group nodes at runtime

Groups can be dynamically created during runtime in the diagram by invoking the diagram.group method. To initiate this process, first, select the nodes that you intend to include within the group. Subsequently, by utilizing the diagram.group method, the selected nodes will be encapsulated within a newly formed group node.

The following code illustrates how to group at runtime.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { useRef } from "react";
import { DiagramComponent } from "@syncfusion/ej2-react-diagrams";

const nodes = [
    {
        id: 'node1', height: 100, width: 100, offsetX: 100, offsetY: 100, annotations: [{ content: 'Node1' }]
    },
    {
        id: 'node2', height: 100, width: 100, offsetX: 200, offsetY: 200, annotations: [{ content: 'Node2' }]
    },
    {
        id: 'node3', height: 100, width: 100, offsetX: 300, offsetY: 300, annotations: [{ content: 'Node3' }]
    },
];

function App() {
    const diagramRef = useRef(null);
    const group = () => {
        //Groups the selected nodes and connectors.
        diagramRef.current.group();
    }
    return (
        <div>
            <button onClick={group}>Group Selected Nodes</button>
            <DiagramComponent id="diagram" ref={diagramRef} width="100%"
                height="900px" nodes={nodes}
                created={() => {
                    diagramRef.current.selectAll();
                }}
            />
        </div>
    );
}

const root = ReactDOM.createRoot(document.getElementById('container'));
root.render(<App />);
import * as React from "react";
import * as ReactDOM from "react-dom";
import { useRef } from "react";
import { DiagramComponent, NodeModel } from "@syncfusion/ej2-react-diagrams";

const nodes: NodeModel[] = [
    {
        id: 'node1', height: 100, width: 100, offsetX: 100, offsetY: 100, annotations: [{ content: 'Node1' }]
    },
    {
        id: 'node2', height: 100, width: 100, offsetX: 200, offsetY: 200, annotations: [{ content: 'Node2' }]
    },
    {
        id: 'node3', height: 100, width: 100, offsetX: 300, offsetY: 300, annotations: [{ content: 'Node3' }]
    },
];

function App() {
    const diagramRef = useRef(null);
    const group = () => {
        //Groups the selected nodes and connectors.
        diagramRef.current.group();
    }
    return (
        <div>
            <button onClick={group}>Group Selected Nodes</button>
            <DiagramComponent id="diagram" ref={diagramRef} width="100%"
                height="900px" nodes={nodes}
                created={() => {
                    diagramRef.current.selectAll();
                }}
            />
        </div>
    );
}

const root = ReactDOM.createRoot(document.getElementById('container'));
root.render(<App />);

UnGroup nodes at runtime

Group node can be unGrouped dynamically, by using the diagram.unGroup method. The following code example shows how to unGroup group node at runtime.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { useRef } from "react";
import { DiagramComponent } from "@syncfusion/ej2-react-diagrams";

const nodes = [

        height: 100,
        style: {
            strokeColor: '#6BA5D7',
            fill: '#6BA5D7',
        },
        annotations: [{
            content: 'rectangle1',
        }],
    },
    {
        id: 'rectangle2',
        offsetX: 200,
        offsetY: 200,
        width: 100,
        height: 100,
        style: {
            strokeColor: '#6BA5D7',
            fill: '#6BA5D7',
        },
        annotations: [{
            content: 'rectangle2',
        }],
    },
    {
        id: 'group',
        children: ['rectangle1', 'rectangle2'],
    }
];

function App() {
    const diagramRef = useRef(null);
    const unGroup = () => {
        //Ungroups the selected nodes and connectors.
        diagramRef.current.unGroup();
    }
    return (
        <div>
            <button onClick={unGroup}>UnGroup</button>
            <DiagramComponent id="diagram" ref={diagramRef} width="100%"
                height="600px" nodes={nodes}
                created={() => {
                    diagramRef.current.select([diagramRef.current.getObject('group')]);
                }}
            />
        </div>
    );
}

const root = ReactDOM.createRoot(document.getElementById('container'));
root.render(<App />);
import * as React from "react";

        }],
    },
    {
        id: 'group',
        children: ['rectangle1', 'rectangle2'],
    }
];

function App() {
    const diagramRef = useRef(null);
    const unGroup = () => {
        //Ungroups the selected nodes and connectors.
        diagramRef.current.unGroup();
    }
    return (

Add collection of group nodes at runtime

  • The collection of group nodes can be dynamically added using addElements method.Each time an element is added to the diagram canvas, the collectionChange event will be triggered.

The following code illustrates how to add group nodes collection at runtime.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { useRef } from "react";
import { DiagramComponent } from "@syncfusion/ej2-react-diagrams";

const group = [
    { id: "rectangle1", offsetX: 100, offsetY: 100, width: 100, height: 100, annotations: [{ content: 'node1' }] },
    { id: "rectangle2", offsetX: 200, offsetY: 200, width: 100, height: 100, annotations: [{ content: 'node2' }] },
    { id: 'group', children: ['rectangle1', 'rectangle2'] },
    { id: "rectangle3", offsetX: 400, offsetY: 400, width: 100, height: 100, annotations: [{ content: 'node1' }] },
    { id: "rectangle4", offsetX: 500, offsetY: 500, width: 100, height: 100, annotations: [{ content: 'node2' }] },
    { id: 'group2', children: ['rectangle3', 'rectangle4'], padding: { left: 10, right: 10, top: 10, bottom: 10 } },
];

function App() {
    const diagramRef = useRef(null);
    return (
        <div>
            <DiagramComponent id="diagram" ref={diagramRef} width="100%" height="500px"
                created={() => {

                    diagramRef.current.addElements(group);
                }}
            />
        </div>
    );
}

const root = ReactDOM.createRoot(document.getElementById('container'));
root.render(<App />);
import * as React from "react";
import * as ReactDOM from "react-dom";
import { useRef } from "react";
import { DiagramComponent, NodeModel } from "@syncfusion/ej2-react-diagrams";

const group: NodeModel[] = [
    { id: "rectangle1", offsetX: 100, offsetY: 100, width: 100, height: 100, annotations: [{ content: 'node1' }] },
    { id: "rectangle2", offsetX: 200, offsetY: 200, width: 100, height: 100, annotations: [{ content: 'node2' }] },
    { id: 'group', children: ['rectangle1', 'rectangle2'] },

    { id: "rectangle4", offsetX: 500, offsetY: 500, width: 100, height: 100, annotations: [{ content: 'node2' }] },
    { id: 'group2', children: ['rectangle3', 'rectangle4'], padding: { left: 10, right: 10, top: 10, bottom: 10 } },
];

function App() {
    const diagramRef = useRef(null);
    return (
        <div>
            <DiagramComponent id="diagram" ref={diagramRef} width="100%" height="500px"

root.render(<App />);

Add/Remove children from group

Add children To group at runtime

A childNode can be added to the specified Group at runtime by utilizing the diagram method diagram.addChildToGroup.

This functionality is achieved by passing the group and existing children as arguments to the method.

The following code illustrates how a child node and a group node can be passed as arguments to the method and executed at runtime.

diagram.addChildToGroup(groupNode, childNode);

Remove children from group at runtime

A specific child from a group node can be removed at runtime by utilizing the diagram method diagram.removeChildFromGroup.

This functionality is achieved by passing the group and its children as arguments to the method.

The following code illustrates how a child node is removed from a group at runtime.

diagram.removeChildFromGroup (groupNode, childNode);

Group flip

The flip functionality for a group node works similarly to that of normal nodes. However, when flipping a group node, the flip of its child nodes is combined with the group’s flip. This combination ensures that the child nodes inherit the group’s flip while retaining their own individual flips.

Example:

  • If a child node’s flip is set to Vertical and the group node’s flip is set to Horizontal, the resulting flip for the child node will be a combination of Vertical and Horizontal (effectively a “both” flip).
  • This ensures that the child nodes’ orientations adapt dynamically based on the group’s flip while maintaining their unique flip settings.

The following example shows how to apply flip for group node.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { useRef } from "react";
import { DiagramComponent,FlipDirection } from "@syncfusion/ej2-react-diagrams";
const nodes = [
    {

        height: 70,
        offsetX: 100,
        offsetY: 100,
        //Sets the flip as Vertical
        flip: FlipDirection.Vertical,
        shape: {
          type: 'Basic',
          shape: 'RightTriangle',
        },
        style: {
          fill: '#6BA5D7',
        },
      },
      {
        id: 'node2',

Group flip mode

The flipMode of a group node also behave similarly to those of normal nodes. However,When you apply a flip mode to a group node, it takes precedence over any flip mode set on its child nodes, overriding their individual settings.

For example, in the below code,
the flipMode for the child node Node1 is set to LabelText.
The flipMode for the group node is set to Label.
As a result, the effective flipMode for both the child node and the group node will be Label, as the group node’s flipMode overrides the child’s.

Nested group

Nested groups are essentially groups within groups, where a group can contain other groups as its children, creating a hierarchy that helps manage complexity and relationships between different elements.

Container

Containers are used to automatically measure and arrange the size and position of the child elements in a predefined manner. There are two types of containers available.

Canvas

  • The canvas panel supports absolute positioning and provides the least layout functionality to its contained diagram elements.

  • Canvas allows you to position its contained elements by using the margin and alignment properties.

  • Rendering alone possible in canvas container.

  • It allows elements to be either vertically or horizontally aligned.

  • Child can be defined with the collection canvas.children property.

  • Basic element can be defined with the collection of basicElements.

The following code illustrates how to add canvas panel.

import * as React from "react";
import * as ReactDOM from "react-dom";
import {useRef} from "react";
import { DiagramComponent, DiagramElement, Canvas } from "@syncfusion/ej2-react-diagrams";
let canvas;
let child1;
let child2;
canvas = new Canvas();
canvas.pivot = {
    x: 0,
    y: 0
};
canvas.offsetX = 75;
canvas.offsetY = 75;
canvas.style.fill = '#6BA5D7';
child1 = new DiagramElement();
child1.id = 'child1';
child1.width = 100;
child1.height = 100;
child1.margin.left = child1.margin.top = 10;
child2 = new DiagramElement();
child2.id = 'child2';
child2.width = 100;
child2.height = 100;
child2.margin.left = 190;
child2.margin.right = 5;
child2.margin.top = 190;
child2.margin.bottom = 5;
canvas.children = [child1, child2];
function App() {
    const diagramInstance = useRef(null);
    return (<DiagramComponent id="diagram" ref={diagramInstance} mode={'SVG'} width={'1000px'} height={'600px'} 
    // Defines the basic elements
    basicElements={[canvas]}/>);
}

Stack

  • Stack panel is used to arrange its children in a single line or stack order, either vertically or horizontally.

  • It controls spacing by setting margin properties of child and padding properties of group. By default, a stack panel’s orientation is vertical.

The following code illustrates how to add a stack panel.

import * as React from "react";
import * as ReactDOM from "react-dom";

            }]
    },];

let getTextElement = (text) => {
    let textElement = new TextElement();
    textElement.id = "text" + count;
    textElement.width = 50;
    textElement.height = 20;
    textElement.content = text;
    count++;
    return textElement;
};

Difference between a basic group and containers

Group Container
It arranges the child elements based on the child elements position and size properties. Each container has a predefined behavior to measure and arrange its child elements. Canvas and stack containers are supported in the diagram.
The Padding, Min, and Max Size properties are not applicable for basic group. It is applicable for container.
The Children’s margin and alignment properties are not applicable for basic group. It is applicable for container.

Interaction

Group node interactions can be performed similarly to normal nodes. Fundamental diagram interactions like selecting, dragging, resizing, and rotating apply equally to group nodes. For more informatation refer to the nodes interactions

Selecting a Node Group

When a child element within a node group is clicked, the entire contained node group is selected instead of the individual child element. Subsequent clicks on the selected element change the selection from top to bottom within the hierarchy, moving from the parent node group to its children.

Events

The events triggered when interacting with group nodes are similar to those for individual nodes. For more information, refer to the nodes events
