Linear Flow in Angular Stepper component

6 Jan 20245 minutes to read

The Stepper component enables users to progress sequentially through each step, ensuring navigation from one step to the next in a linear way by setting the linear property to true. The default value is false allowing navigation between any steps and vice versa.

The example demonstrates the functionality of both linear and non-linear flow in the Stepper.

app.component.ts

import { Component, ViewChild } from "@angular/core";
import { StepperComponent } from '@syncfusion/ej2-angular-navigations';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent  {
  @ViewChild('ejStepper') stepper: StepperComponent | any;

  public updateLinear(args: any): void {
    this.stepper.linear = (/true/).test(args.currentTarget.value) ? true : false;
    this.stepper.reset();
  };
}

app.module.ts

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";

// Import Syncfusion Stepper module from navigation package.
import {  StepperModule, StepperAllModule } from "@syncfusion/ej2-angular-navigations";

import { AppComponent } from "./app.component";

@NgModule({
  imports: [BrowserModule, StepperAllModule, StepperModule ], // Registering EJ2 Stepper Module.
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {}

main.ts

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

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
