Getting Started with Breadcrumb Web Component
Smart UI for Web Components is distributed as smart-webcomponents NPM package. You can also get the full download from our website with all demos from the Download page.Setup the Breadcrumb
Smart UI for Web Components is distributed as smart-webcomponents NPM package
- Download and install the package.
npm install smart-webcomponents
- Once installed, import the Breadcrumb module in your application.
<script type="module" src="node_modules/smart-webcomponents/source/modules/smart.breadcrumb.js"></script>
-
Adding CSS reference
The smart.default.css CSS file should be referenced using following code.
<link rel="stylesheet" type="text/css" href="node_modules/smart-webcomponents/source/styles/smart.default.css" />
- Add the Breadcrumb tag to your Web Page
<smart-breadcrumb id="breadcrumb"></smart-breadcrumb>
- Create the Breadcrumb Component
<script type="module"> Smart('#breadcrumb', class { get properties() { return [object Object] } }); </script>
Another option is to create the Breadcrumb is by using the traditional Javascript way:
const breadcrumb = document.createElement('smart-breadcrumb'); breadcrumb.disabled = true; document.body.appendChild(breadcrumb);
Smart framework provides a way to dynamically create a web component on demand from a DIV tag which is used as a host. The following imports the web component's module and creates it on demand, when the document is ready. The #breadcrumb is the ID of a DIV tag.
import "../../source/modules/smart.breadcrumb.js"; document.readyState === 'complete' ? init() : window.onload = init; function init() { const breadcrumb = new Smart.Breadcrumb('#breadcrumb', [object Object]); }
- Open the page in your web server.
Create, Append, Remove, Get/Set Property, Invoke Method, Bind to Event
Create a new element:
const breadcrumb = document.createElement('smart-breadcrumb');
Append it to the DOM:
document.body.appendChild(breadcrumb);
Remove it from the DOM:
breadcrumb.parentNode.removeChild(breadcrumb);
Set a property:
breadcrumb.propertyName = propertyValue;
Get a property value:
const propertyValue = breadcrumb.propertyName;
Invoke a method:
breadcrumb.methodName(argument1, argument2);
Add Event Listener:
const eventHandler = (event) => { // your code here. }; breadcrumb.addEventListener(eventName, eventHandler);
Remove Event Listener:
breadcrumb.removeEventListener(eventName, eventHandler, true);
Using with Typescript
Smart Web Components package includes TypeScript definitions which enables strongly-typed access to the Smart UI Components and their configuration.
Inside the download package, the typescript directory contains .d.ts file for each web component and a smart.elements.d.ts typescript definitions file for all web components. Copy the typescript definitions file to your project and in your TypeScript file add a reference to smart.elements.d.ts

Setup Angular Environment
Angular provides the easiest way to set angular CLI projects using Angular CLI tool.
Install the CLI application globally to your machine.
npm install -g @angular/cli
Create a new Application
ng new smart-angular-breadcrumb
Navigate to the created project folder
cd smart-angular-breadcrumb
Setup the Breadcrumb
Smart UI for Angular is distributed as smart-webcomponents-angular NPM package
- Download and install the package.
npm install smart-webcomponents-angular
- Once installed, import the BreadcrumbModule in your application root or feature module.
app.module.ts
import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { BreadcrumbModule } from 'smart-webcomponents-angular/breadcrumb'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, BreadcrumbModule ], bootstrap: [ AppComponent ], entryComponents: [ AppComponent ] }) export class AppModule { }
- Adding CSS reference
The following CSS file is available in ../node_modules/smart-webcomponents-angular/ package folder. This can be referenced in [src/styles.css] using following code.@import 'smart-webcomponents-angular/source/styles/smart.default.css';
Another way to achieve the same is to edit the angular.json file and in the styles add the style."styles": [ "node_modules/smart-webcomponents-angular/source/styles/smart.default.css" ]
-
Example
app.component.html
<smart-breadcrumb #breadcrumb id="breadcrumb1" add-new-item allow-drag allow-drop close-buttons data-source='[{ "label": "Planets", "value": "A" }, { "label": "Continents", "value": "B" }, { "label": "Countries", "value": "C" }, { "label": "States", "value": "D" }, { "label": "Cities", "value": "E" }]'></smart-breadcrumb> <br /> <smart-breadcrumb #breadcrumb2 id="breadcrumb2" allow-drag allow-drop close-buttons data-source='[{ "label": "Email", "value": "alternate_email" }, { "label": "Phone", "value": "phone" }, { "label": "TV", "value": "tv" }, { "label": "Video game", "value": "videogame_asset" }, { "label": "Laptop", "value": "laptop" }]' item-template="breadcrumb2Template"></smart-breadcrumb> <br /> <smart-breadcrumb #breadcrumb3 id="breadcrumb3" minimize-width="150" allow-drag allow-drop close-buttons data-source='[{ "label": "Planets", "value": "A" }, { "label": "Continents", "value": "B" }, { "label": "Countries", "value": "C" }, { "label": "States", "value": "D" }, { "label": "Cities", "value": "E" }]'></smart-breadcrumb>
app.component.ts
import { Component, ViewChild, OnInit, AfterViewInit } from '@angular/core'; import { BreadcrumbComponent } from 'smart-webcomponents-angular/breadcrumb'; @Component({ selector: 'app-root', templateUrl: './app.component.html' }) export class AppComponent implements AfterViewInit, OnInit { @ViewChild('breadcrumb', { read: BreadcrumbComponent, static: false }) breadcrumb: BreadcrumbComponent; @ViewChild('breadcrumb2', { read: BreadcrumbComponent, static: false }) breadcrumb2: BreadcrumbComponent; @ViewChild('breadcrumb3', { read: BreadcrumbComponent, static: false }) breadcrumb3: BreadcrumbComponent; ngOnInit(): void { // onInit code. } ngAfterViewInit(): void { // afterViewInit code. } }
app.module.ts
import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { BreadcrumbModule } from 'smart-webcomponents-angular/breadcrumb'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, BreadcrumbModule ], bootstrap: [ AppComponent ], entryComponents: [ AppComponent ] }) export class AppModule { }

The easiest way to start with React is to use create-react-app. To scaffold your project structure, follow the installation instructions.
npm install -g create-react-app create-react-app my-app cd my-app npm start
Preparation
Open src/App.js andsrc/App.css
- Remove everything inside the App div tag in src/App.js:
<div className="App"> </div>
- Remove the logo.svg import
- Remove the contents of src/App.css
- Remove src/logo.svg
Setup the Breadcrumb
Smart UI for React is distributed as smart-webcomponents-react NPM package
- Download and install the package.
npm install smart-webcomponents-react
Once installed, import the React Breadcrumb Component and CSS files in your application and render it
app.js
import 'smart-webcomponents-react/source/styles/smart.default.css'; import React from "react"; import ReactDOM from "react-dom"; import { Breadcrumb } from 'smart-webcomponents-react/breadcrumb'; class App extends React.Component { componentDidMount() { } render() { return ( <div> <Breadcrumb ref="breadcrumb" id="breadcrumb1" addNewItem allowDrag allowDrop closeButtons dataSource='[{ "label": "Planets", "value": "A" }, { "label": "Continents", "value": "B" }, { "label": "Countries", "value": "C" }, { "label": "States", "value": "D" }, { "label": "Cities", "value": "E" }]'></Breadcrumb> <br /> <Breadcrumb ref="breadcrumb2" id="breadcrumb2" allowDrag allowDrop closeButtons data-source='[{ "label": "Email", "value": "alternate_email" }, { "label": "Phone", "value": "phone" }, { "label": "TV", "value": "tv" }, { "label": "Video game", "value": "videogame_asset" }, { "label": "Laptop", "value": "laptop" }]' ></Breadcrumb> <br /> <Breadcrumb ref="breadcrumb3" id="breadcrumb3" minimizeWidth="150" allowDrag allowDrop closeButtons dataSource='[{ "label": "Planets", "value": "A" }, { "label": "Continents", "value": "B" }, { "label": "Countries", "value": "C" }, { "label": "States", "value": "D" }, { "label": "Cities", "value": "E" }]'></Breadcrumb> </div> ); } } ReactDOM.render(<App />, document.querySelector("#root")); export default App;

Getting Started with Vue Breadcrumb Component
Setup Vue Environment
We will use vue-cli to get started. Let's install vue-cli
npm install -g @vue/cli
Then we can start creating our Vue.js projects with:
vue create my-project
Setup the Breadcrumb
Open the "my-project" folder and run:
npm install smart-webcomponents
Setup with Vue 3.x
-
Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.
Open src/main.js in your favorite text editor and change its contents to the following:
main.js
import { createApp } from 'vue' import App from './App.vue' const app = createApp(App) app.config.isCustomElement = tag => tag.startsWith('smart-'); app.mount('#app')
-
Open src/App.vue in your favorite text editor and change its contents to the following:
App.vue
<template> <div class="vue-root"> <smart-breadcrumb id="breadcrumb1" add-new-item allow-drag allow-drop close-buttons data-source="[{ 'label': 'Planets', 'value': 'A' }, { 'label': 'Continents', 'value': 'B' }, { 'label': 'Countries', 'value': 'C' }, { 'label': 'States', 'value': 'D' }, { 'label': 'Cities', 'value': 'E' }]" ></smart-breadcrumb> <br /> <smart-breadcrumb id="breadcrumb2" allow-drag allow-drop close-buttons data-source="[{ 'label': 'Email', 'value': 'alternate_email' }, { 'label': 'Phone', 'value': 'phone' }, { 'label': 'TV', 'value': 'tv' }, { 'label': 'Video game', 'value': 'videogame_asset' }, { 'label': 'Laptop', 'value': 'laptop' }]" item-template="breadcrumb2Template" ></smart-breadcrumb> <br /> <smart-breadcrumb id="breadcrumb3" minimize-width="150" allow-drag allow-drop close-buttons data-source="'[{ 'label': 'Planets', 'value': 'A' }, { 'label': 'Continents', 'value': 'B' }, { 'label': 'Countries', 'value': 'C' }, { 'label': 'States', 'value': 'D' }, { 'label': 'Cities', 'value': 'E' }]" ></smart-breadcrumb> <template id="breadcrumb2Template"> <i class="material-icons">{{value}}</i> {{label}} </template> </div> </template> <script> import { onMounted } from "vue"; import "smart-webcomponents/source/styles/smart.default.css"; import "smart-webcomponents/source/modules/smart.breadcrumb.js"; export default { name: "app", setup() { onMounted(() => { const breadcrumb1 = document.getElementById("breadcrumb1"); let newItems = 0; breadcrumb1.addEventListener("addNewItem", function() { if (newItems === 0) { breadcrumb1.addItem({ index: this.dataSource.length, label: "Districts", value: "F" }); newItems++; } else if (newItems === 1) { breadcrumb1.addItem({ index: this.dataSource.length, label: "Blocks", value: "G" }); breadcrumb1.addNewItem = false; } }); breadcrumb1.addEventListener("dragEnd", function(event) { if (!breadcrumb1.contains(event.detail.target)) { breadcrumb1.removeItem(event.detail.item); } }); }); } }; </script> <style> #breadcrumb2 { --smart-breadcrumb-item-height: 50px; width: 800px; } #breadcrumb2 .smart-breadcrumb-item-label { display: flex; align-items: center; } .material-icons { margin-right: 5px; padding: 5px; width: 34px; height: 34px; background-color: var(--smart-success); border-radius: 100%; } #breadcrumb3 { width: 100px; } </style>
We can now use the smart-breadcrumb with Vue 3. Data binding and event handlers will just work right out of the box.
Setup with Vue 2.x
-
Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.
Open src/main.js in your favorite text editor and change its contents to the following:
main.js
import Vue from 'vue' import App from './App.vue' Vue.config.productionTip = false Vue.config.ignoredElements = [ 'smart-breadcrumb' ] new Vue({ render: h => h(App), }).$mount('#app')
-
Open src/App.vue in your favorite text editor and change its contents to the following:
App.vue
We have bound the properties of the smart-breadcrumb to values in our Vue component.
Running the Vue application
Start the app withnpm run serveand open localhost:8080 in your favorite web browser to see the output below:
