3 Nov 202311 minutes to read

This section explains how to create a simple Breadcrumb, and configure its available functionalities in TypeScript using Essential JS 2 quickstart seed repository.

This application is integrated with the webpack.config.js configuration and uses the latest version of the webpack-cli. It requires node v14.15.0 or higher. For more information about webpack and its features, refer to the webpack documentation.

Dependencies

The following list of dependencies are required to use the Breadcrumb component in your application.

|-- @syncfusion/ej2-navigations
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-lists
    |-- @syncfusion/ej2-inputs
    |-- @syncfusion/ej2-popups
        |-- @syncfusion/ej2-buttons

Set up development environment

Open the command prompt from the required directory, and run the following command to clone the Syncfusion JavaScript (Essential JS 2) quickstart project from GitHub.

git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack- ej2-quickstart

After cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.

cd ej2-quickstart

Add Syncfusion JavaScript packages

Syncfusion JavaScript (Essential JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion JavaScript (Essential JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.

The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.

npm install

Import the Syncfusion CSS styles

To render Breadcrumb component, need to import navigations and its dependent components styles as given below in the ~/src/styles/styles.css file, as shown below:

@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-lists/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-navigations/styles/material.css";

Adding Breadcrumb component to the application

Open the application in Visual Studio Code and add the Syncfusion JavaScript UI controls.

Add the HTML div tag with its id attribute as breadcrumb in your index.html file to initialize the Breadcrumb.

[src/index.html]

<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2 - Breadcrumb</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
    <meta name="description" content="Essential JS 2" />
    <meta name="author" content="Syncfusion" />
    <link rel="shortcut icon" href="resources/favicon.ico" />
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
</head>

<body>
    <div>
        <div id="breadcrumb"></div>
    </div>
</body>

</html>

Import the Breadcrumb component in your app.ts file and initialize it with the #breadcrumb.

[src/app/app.ts]

import { BreadcrumbItemModel, Breadcrumb } from '@syncfusion/ej2-navigations';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

    new Breadcrumb({
       enableNavigation: false
    }, '#breadcrumb');

Run the application

Run the application in the browser using the following command:

npm start

The following example shows a basic Breadcrumb component.

Adding Breadcrumb items to the project

Use items property to bind items for Breadcrumb component. The below example demonstrates the basic rendering of Breadcrumb with items support.

<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
    <meta name="description" content="Essential JS 2" />
    <meta name="author" content="Syncfusion" />
    <link href="https://cdn.syncfusion.com/ej2/23.2.4/ej2-base/styles/material.css" rel="stylesheet" />
    <link href="https://cdn.syncfusion.com/ej2/23.2.4/ej2-popups/styles/material.css" rel="stylesheet" />
    <link href="https://cdn.syncfusion.com/ej2/23.2.4/ej2-navigations/styles/material.css" rel="stylesheet" />

    <!--style reference from app-->
    <link href="styles.css" rel="stylesheet" />

    <!--system js reference and configuration-->
    <script src="https://cdnjs.cloudflare.com/ajax/libs/systemjs/0.19.38/system.js"></script>
    <script src="systemjs.config.js"></script>
<script src="https://cdn.syncfusion.com/ej2/syncfusion-helper.js" type ="text/javascript"></script>
</head>
<body>
    <div id='loader'>LOADING....</div>
    <div id='container'>
        <div class="control-section">
            <ul id="breadcrumb"></ul>
        </div>
    </div>
</body>

</html>

Enable or Disable Navigation

This feature enables or disables the item navigation. By default, the navigation will be enabled when setting Url property. To prevent breadcrumb item navigation, set enableNavigation property as false in Breadcrumb. The below example shows enabling and disabling the navigation of Breadcrumb items.

import { BreadcrumbItemModel, Breadcrumb } from '@syncfusion/ej2-navigations';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

//Breadcrumb items definition

let items: BreadcrumbItemModel[] = [
    {
        iconCss: 'e-icons e-home',
        url: "https://ej2.syncfusion.com/demos",
    },
    {
        text: "Components",
        url: "https://ej2.syncfusion.com/demos/#/material/grid/grid-overview",
    },
    {
        text: "Navigations",
        url: "https://ej2.syncfusion.com/demos/#/material/breadcrumb/default",
    },
    {
        text: "Breadcrumb",
        url: "./breadcrumb/default",
    }
];

new Breadcrumb({
    items: items,
    enableNavigation: false
}, '#breadcrumb');

new Breadcrumb({
    items: items,
}, '#breadcrumb2');
