Data binding in Angular Breadcrumb component

27 Apr 20246 minutes to read

Items as tag directive

The Angular Breadcrumb contains e-breadcrumb-items and e-breadcrumb-item tags to render items for the component. To bind items, use e-breadcrumb-items tag and e-breadcrumb-item tag to bind properties for breadcrumb items.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { BreadcrumbModule } from '@syncfusion/ej2-angular-navigations'



import { Component } from '@angular/core';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

@Component({
imports: [ BreadcrumbModule],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
            <!-- To Render Breadcrumb with items. -->
            <ejs-breadcrumb [enableNavigation]="false">
                <e-breadcrumb-items>
                    <e-breadcrumb-item text="Home" url="https://ej2.syncfusion.com/home/angular.html"></e-breadcrumb-item>
                    <e-breadcrumb-item text="Components" url="https://ej2.syncfusion.com/angular/demos/#/material/grid/over-view"></e-breadcrumb-item>
                    <e-breadcrumb-item text="Navigations" url="https://ej2.syncfusion.com/angular/demos/#/material/breadcrumb/default"></e-breadcrumb-item>
                    <e-breadcrumb-item text="Breadcrumb" url="./breadcrumb/default"></e-breadcrumb-item>
                </e-breadcrumb-items>
            </ejs-breadcrumb></div>`
})

export class AppComponent {}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Items based on current Url

The breadcrumb items can be generated from the current URL of the page, if the url property is not provided or when the user does not specify the breadcrumb items using the BreadcrumbItemDirective tag. The following example shows the breadcrumb items that are generated based on the current URL.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { BreadcrumbModule } from '@syncfusion/ej2-angular-navigations'



import { Component } from '@angular/core';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

@Component({
imports: [ BreadcrumbModule],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
            <!-- To Render Breadcrumb. -->
            <ejs-breadcrumb [enableNavigation]="false"></ejs-breadcrumb></div>`
})

export class AppComponent {}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

This sample is hosted in different location, so the Breadcrumb Component is rendered with different location instead of the actual location.

Static URL

The breadcrumb items can be generated by providing the url property in the component, if the user does not specify the breadcrumb items using the BreadcrumbItemDirective tag. The following example shows the breadcrumb items generated from the provided url in the component.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { BreadcrumbModule } from '@syncfusion/ej2-angular-navigations'



import { Component } from '@angular/core';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

@Component({
imports: [ BreadcrumbModule],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
            <!-- To Render Breadcrumb. -->
            <ejs-breadcrumb [enableNavigation]="false" url="https://ej2.syncfusion.com/angular/demos/breadcrumb/bind-to-location"></ejs-breadcrumb></div>`
})

export class AppComponent {}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Customize text when generated items using Url

The breadcrumb items text can be customized by using the beforeItemRender event. In the following example, bind-to-location text was customized as location.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { BreadcrumbModule } from '@syncfusion/ej2-angular-navigations'



import { Component } from '@angular/core';
import { enableRipple } from '@syncfusion/ej2-base';
import { BreadcrumbBeforeItemRenderEventArgs } from '@syncfusion/ej2-navigations';

enableRipple(true);

@Component({
imports: [ BreadcrumbModule],


standalone: true,
    selector: 'app-root',
    template: `<div class="e-section-control">
            <!-- To Render Breadcrumb with items. -->
            <ejs-breadcrumb [enableNavigation]="false" (beforeItemRender)="beforeItemRenderHandler($event)" url="https://ej2.syncfusion.com/angular/demos/breadcrumb/bind-to-location"></ejs-breadcrumb></div>`
})

export class AppComponent {
    beforeItemRenderHandler(args: BreadcrumbBeforeItemRenderEventArgs): void {
        if (args.item.text === 'bind-to-location') {
            args.item.text = 'location';
        }
    }
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
