The o-breadcrumb component is used as a navigational aid when using OntimizeWeb forms. This component listens to route changes on the application and builds links to keep track of the locations the user is navigating through.

Initialize

For using the breadcrum component it is necessary to initialize the NavigationService in order to gather the required information for building the breadcrumb component. For initializing the Navigation Service, just call the method initialize on the constructor of your application main component like the example below.

  import { Component, Injector } from '@angular/core';
  import { NavigationService } from 'ontimize-web-ngx';

  @Component({
    selector: 'o-app',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.scss']
  })
  export class AppComponent {

    constructor(protected injector: Injector) {
      this.injector.get(NavigationService).initialize();
    }

  }

Example 

    <o-breadcrumb [form]="myForm" label-columns="NAME;SURNAME" separator=" "></o-breadcrumb>

    <o-form #myForm service="myService" entity="myEntity" keys="USERID" columns="USERID;NAME;SURNAME;ADDRESS">

        ...

    </o-form>

If the form attibute is not present, the text shown in the breadcrumb label will be the corresponding route item for the component where the breadcrumb is placed.
