1 NPM Install

Install the smart-webcomponents-angular package:

npm install smart-webcomponents-angular

2 Register styles

Add the default Smart UI stylesheet to angular.json -> projects -> <your-project> -> architect -> build -> options -> styles (merge with existing entries):

"styles": [
		"node_modules/smart-webcomponents-angular/source/styles/smart.default.css"
	]

Add optional theme CSS from the same package after smart.default.css if you use Bootstrap, Fluent, or other bundled themes.

3 Import the Angular module

Import BreadcrumbModule from smart-webcomponents-angular/breadcrumb: use @Component.imports for standalone, or add it to your AppModule (or feature module) imports array for NgModule apps.

import { BreadcrumbModule } from 'smart-webcomponents-angular/breadcrumb';

4 Root component (standalone)

Add BreadcrumbModule to your root standalone component (src/app/app.ts). Snippet from Smart UI demos (paths normalized to app.html / App where applicable):

 import { Component, ViewChild, OnInit, AfterViewInit } from '@angular/core';
import { BreadcrumbComponent } from 'smart-webcomponents-angular/breadcrumb';

import { BreadcrumbModule } from 'smart-webcomponents-angular/breadcrumb';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [ BreadcrumbModule ],
  templateUrl: './app.html',
  styleUrl: './app.css'
})

export class App 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.
		
    }
}

Boot the app with bootstrapApplication from src/main.ts and an ApplicationConfig in src/app/app.config.ts as generated by the CLI.

5 Template (standalone)

Use your markup in src/app/app.html (or inline template). Bind properties and events on smart-breadcrumb as needed:

 <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>

6 NgModule bootstrap (also supported)

Same npm package and angular.json styles as steps 1-2. Put BreadcrumbModule on your NgModule.imports instead of @Component.imports, and bootstrap with bootstrapModule(AppModule).

The demo sources bundled for this widget use standalone only (there is no app.module.ts in that folder). NgModule is fully supported: put BreadcrumbModule from smart-webcomponents-angular/breadcrumb on NgModule.imports, make your root component non-standalone (remove standalone: true and move widget modules from @Component.imports to the module), and bootstrap with platformBrowserDynamic().bootstrapModule(AppModule).

Minimal main.ts + app.module.ts pairing (adjust paths to match your CLI layout):

src/main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';

platformBrowserDynamic().bootstrapModule(AppModule).catch((err) => console.error(err));

src/app/app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { BreadcrumbModule } from 'smart-webcomponents-angular/breadcrumb';

@NgModule({
	declarations: [ AppComponent ],
	imports: [ BrowserModule, BreadcrumbModule ],
	bootstrap: [ AppComponent ]
})
export class AppModule { }

Reuse the template and class logic from steps 4-5 in AppComponent, configured for declarations + NgModule.imports instead of a standalone @Component.
