Symbol palette in EJ2 JavaScript Diagram control

2 Aug 202424 minutes to read

The symbolPalette is a gallery of reusable symbols and diagram elements that can be dragged and dropped on the diagram surface multiple times.

Create symbol palette

The width and height properties of the symbol palette allows you to define the size of the symbol palette.

ej.diagrams.Diagram.Inject(ej.diagrams.SymbolPalette);
//Initializes the symbol palette
var palette = new ej.diagrams.SymbolPalette({
    width: '100%',
    height: '700px',
},'#element');

Add nodes and palettes to SymbolPalette

The collection of predefined symbols can be added to palettes using the symbols property.

A palette displays a group of related symbols and textually annotates the group with its header. A Palettes can be added as a collection of symbol groups.

To initialize a palette, define a JSON object with the unique property ID. Additionally, include the symbols property, which contains an array of different symbols.

The following code example illustrates how to define symbols in a palette and how to add them to the symbol palette:

/**

Add group nodes in symbol palette

The symbol palette supports adding group nodes. To add group nodes to the palette, the child nodes should be defined first, followed by the parent node. Refer to the following code to see how to render group nodes in the symbol palette:

/**
 * Default symbol palette sample
 */
function getGroupNodes() {
    var nodes = [
      {
        id: 'child1',
        width: 50,
        height: 50,
        style: { fill: 'green' },
        offsetX: 100,
        offsetY: 100,
      },
      {
        id: 'child2',
        width: 50,
        height: 50,
        style: { fill: 'yellow' },
        offsetX: 170,
        offsetY: 110,
      },
      {
        id: 'group1',
        children: ['child1', 'child2'],
        padding: { left: 10, right: 10, top: 10, bottom: 10 },
      },
      {
        id: 'child3',
        width: 70,
        height: 40,
        style: { fill: 'pink' },
        offsetX: 100,
        offsetY: 150,
      },
      {
        id: 'child4',
        width: 70,
        height: 40,
        style: { fill: 'orange' },
        offsetX: 100,
        offsetY: 200,
      },
      {
        id: 'group2',
        children: ['child3', 'child4'],
        padding: { left: 10, right: 10, top: 10, bottom: 10 },
      },

Add symbols to palette at runtime

Symbols can be added to palette at runtime by using public method, addPaletteItem. The following example shows how to add shapes to the palette at runtime.

//Initialize basic shapes palette
function getBasicShapes() {
  var basicShapes = [
    {
      id: 'Rectangle',
      shape: { type: 'Basic', shape: 'Rectangle' },
      style: { strokeWidth: 2 },
    },
    {
      id: 'Ellipse',
      shape: { type: 'Basic', shape: 'Ellipse' },
      style: { strokeWidth: 2 },
    },
  ];
  return basicShapes;
}
//Initialize the flowshapes for the symbol palette
function getFlowShapes() {
  var flowShapes = [
    {
      id: 'Process',
      shape: { type: 'Flow', shape: 'Process' },
      style: { strokeWidth: 2 },
    },
    {
      id: 'Document',
      shape: { type: 'Flow', shape: 'Document' },
      style: { strokeWidth: 2 },
    },
  ];
  return flowShapes;
}
//Initializes the symbol palette
var symbolPalette = new ej.diagrams.SymbolPalette({
  palettes: [
    {
      id: 'basic',
      expanded: true,
      symbols: getBasicShapes(),
      title: 'Basic Shapes',
    },

      title: 'Flow shapes',
    },
  ],
  symbolHeight: 50,
  symbolWidth: 50,
  symbolPreview: { width: 100, height: 100 },
  expandMode: 'Multiple',
  height: '400px',
  width: '100%',
});
symbolPalette.appendTo('#element');

document.getElementById('addBasicShape').onclick = () => {
  let node = {
    id: 'Plus' + ej.diagrams.randomId(),
    shape: { type: 'Basic', shape: 'Plus' },
  };
  /**
   * parameter 1 - The ID of the palette where the new shape is to be added.
   * parameter 2 - node/connector to be added
   */
  symbolPalette.addPaletteItem('basic', node);
};

document.getElementById('addFlowShape').onclick = () => {

   * parameter 2 - node/connector to be added
   */
  symbolPalette.addPaletteItem('flow', node);
};

Symbol defaults

While adding more symbols such as nodes and connectors to the palette, you can define the default settings for these objects using the getNodeDefaults and the getConnectorDefaults properties of the diagram. These properties allow you to specify default configurations for nodes and connectors, ensuring consistency and saving time when adding multiple symbols. By setting these properties, you can predefine attributes such as size, color, shape for nodes and line style, thickness, for connectors.

In the following example, the fill color of node and target decorator shape of connector is defined in getNodeDefaults and getConnectorDefaults respectively.

/**
 * Default symbol palette sample
 */
//Initialize the flowshapes for the symbol palette
function getFlowShapes() {
    let flowShapes = [
      {
        id: 'process',
        shape: {
          type: 'Flow',
          shape: 'Process',
        },
      },
      {
        id: 'document',
        shape: {
          type: 'Flow',
          shape: 'Document',
        },
      },
      {
        id: 'predefinedprocess',
        shape: {
          type: 'Flow',
          shape: 'PreDefinedProcess',
        },
      },
    ];
    return flowShapes;
  }
  //Initialize connectors for palette
  function getConnectors() {
    let connectors = [
      {
        id: 'Link1',

Add palettes at runtime

You can dynamically add palettes to the symbol palette at runtime to enhance flexibility and customization. This allows you to introduce new groups of symbols as needed without having to reload or reinitialize the diagram. The addPalettes method of the symbol palette enables you to create and configure new palettes programmatically. This method takes parameters that define the palette’s properties, such as the palette ID, title, and the symbols it contains.

Follow the example below to see how to add a palette at runtime.

/**
 * Default symbol palette sample
 */
//Initialize the flowshapes for the symbol palette
function getFlowShapes() {
  let flowShapes = [
    {
      id: 'process',
      shape: {
        type: 'Flow',
        shape: 'Process',
      },
    },
    {
      id: 'document',
      shape: {
        type: 'Flow',
        shape: 'Document',
      },
    },
    {

Remove palettes at runtime

You can remove palettes from the symbol palette at runtime. There are two ways to do this:

  • Use the removePalette method to remove a single palette by its ID.
  • Use the removePalettes method to remove multiple palettes by passing an array of palette IDs as a parameter.

Follow the example below to see how to remove palettes at runtime.

/**
 * Default symbol palette sample
 */
//Initialize the flowshapes for the symbol palette
function getFlowShapes() {
  let flowShapes = [
    {
      id: 'process',
      shape: {
        type: 'Flow',
        shape: 'Process',
      },
    },
    {
      id: 'document',
      shape: {
        type: 'Flow',
        shape: 'Document',
      },
    },
    {
      id: 'predefinedprocess',
      shape: {
        type: 'Flow',
        shape: 'PreDefinedProcess',
      },
    },
  ];
  return flowShapes;
}
//Initialize the basic shapes for the symbol palette
function getBasicShapes() {
  let nodes = [
    {
      id: 'rectangle',
      shape: {
        type: 'Basic',
        shape: 'Rectangle',
      },
    },
    {
      id: 'plus',
      shape: {
        type: 'Basic',
        shape: 'Plus',
      },
    },
    {
      id: 'triangle',
      shape: {
        type: 'Basic',
        shape: 'RightTriangle',
      },
    },
  ];
  return nodes;
}
//Initialize connectors for palette

  let connectors = [

Stretch the symbols into the palette

The fit property defines whether the symbol has to be fit inside the size, that is defined by the symbol palette. For example, when you resize the rectangle in the symbol, ratio of the rectangle size has to be maintained rather changing into square shape. The following code example illustrates how to customize the symbol size.

/**
 * Default symbol palette sample
 */
//Initialize the basicshapes for the symbol palatte
var basicShapes = [{
        id: 'Rectangle',
        shape: {
            type: 'Basic',
            shape: 'Rectangle'
        }
    },
    {
        id: 'Ellipse',
        shape: {
            type: 'Basic',
            shape: 'Ellipse'
        }
    },
    {
        id: 'Hexagon',
        shape: {
            type: 'Basic',
            shape: 'Hexagon'
        }
    }
];
//Initializes the symbol palette
var palette = new ej.diagrams.SymbolPalette({
    expandMode: 'Multiple',
    palettes: [{
        id: 'basic',
        expanded: true,
        symbols: basicShapes,
        title: 'Basic Shapes',
        iconCss: 'e-ddb-icons e-basic'
    }],
    symbolHeight: 80,
    symbolWidth: 80,
    getSymbolInfo: function(symbol) {
        // Enables to fit the content into the specified palette item size
        return {
            fit: true
        };
        // When it is set as false, the element is rendered with actual node size
    },
});
palette.appendTo('#element');
