    breadcrumbs: [new Breadcrumb('Home', '/home')]

Service

To add a breadcrumb item dynamically, use the addItem method declared in the BreadcrumbService:

import { BreadcrumbService } from '@ranout/ngx-breadcrumb';

export class HomeComponent implements OnInit {

  constructor(private breadcrumbService: BreadcrumbService) { }

  ngOnInit(): void {
    this.breadcrumbService.addItem('Page', '/page');
  }

}

Customize

By default, the ngx-breadcrumb component looks like this:

  <nav>
    <ul>
      <li *ngFor="let breadcrumb of breadcrumbs">
        <a [routerLink]="breadcrumb.href">{{ breadcrumb.label }}</a>
      </li>
    </ul>
  </nav>

To customize breadcrumb style, you can add css class on <nav>, <ul>, <li> and <a> tags, with respectively navClass, ulClass, liClass and aClass attributes.

Too, you can add css class for active li element with isActiveClass attribute.

For example, for Bulma:

  <ngx-breadcrumb navClass="breadcrumb" isActiveClass="is-active"></ngx-breadcrumb>

will give the following result if current path is /home:

  <nav class="breadcrumb">
    <ul>
      <li class="is-active">
        <a routerLink="/home">Home</a>
      </li>
      <li>
        <a routerLink="/page">Page</a>
      </li>
    </ul>
  </nav>
