Implementing Syncfusion Angular Stepper

The Syncfusion Angular Stepper component displays a step-by-step process or workflow, ideal for wizards, onboarding, or multi-step forms. This skill guides you through implementing, configuring, and customizing the Stepper component with complete control over step appearance, validation, events, and animations.

When to Use This Skill

Use this skill when:

• Building multi-step wizards or workflows
• Creating step-by-step forms or onboarding flows
• Configuring step validation and linear flow
• Adding icons, labels, and custom templates to steps
• Handling step events (created, stepChanged, stepChanging, beforeStepRender, stepClick)
• Customizing step appearance with animations and styling
• Implementing tooltips, globalization, or RTL support

Component Overview

The Stepper component provides:

• Multiple step types: Default (icons + labels), Indicator Only, Label Only
• Two orientations: Horizontal (default) and Vertical
• Rich event system: created, stepChanged, stepChanging, beforeStepRender, stepClick
• Step validation: Linear flow, completion states, conditional progression
• Customization: Icons, labels, templates, animations, tooltips
• Accessibility: WCAG compliance, keyboard navigation, RTL support

Quick Start Example

import { Component } from "@angular/core";
import { StepperAllModule, StepperModule } from "@syncfusion/ej2-angular-navigations";

@Component({
  imports: [ StepperAllModule, StepperModule ],
  standalone: true,
  selector: 'app-root',
  template: `
    <div class="stepper-container">
      <ejs-stepper>
        <e-steps>
          <e-step label="Cart" iconCss="sf-icon-cart"></e-step>
          <e-step label="Delivery Address" iconCss="sf-icon-transport"></e-step>
          <e-step label="Payment" iconCss="sf-icon-payment"></e-step>
          <e-step label="Confirmation" iconCss="sf-icon-success"></e-step>
        </e-steps>
      </ejs-stepper>
    </div>
  `,
  styles: [`
    .stepper-container {
      padding: 20px;
      max-width: 800px;
      margin: 0 auto;
    }
  `]
})
export class AppComponent { }

Common Patterns

Pattern 1: Wizard with Form Validation

<ejs-stepper (stepChanging)="onStepChanging($event)">
  <e-steps>
    <e-step label="Personal Info"></e-step>
    <e-step label="Contact Details"></e-step>
    <e-step label="Address"></e-step>
    <e-step label="Confirmation"></e-step>
  </e-steps>
</ejs-stepper>

Use the stepChanging event to validate form data before allowing step progression.

Pattern 2: Dynamic Step Icons

<ejs-stepper>
  <e-steps>
    <e-step *ngFor="let step of steps" 
            [label]="step.label" 
            [iconCss]="step.icon"></e-step>
  </e-steps>
</ejs-stepper>

Bind step data dynamically using *ngFor directive.

Pattern 3: Linear Workflow

<ejs-stepper [linear]="true">
  <e-steps>
    <e-step label="Step 1"></e-step>
    <e-step label="Step 2"></e-step>
    <e-step label="Step 3"></e-step>
  </e-steps>
</ejs-stepper>

Enable linear property to enforce sequential progression.

Pattern 4: Event Handling

onStepChanged(args: StepperChangedEventArgs) {
  console.log(`Active step index: ${args.activeStep}`);
}

onStepChanging(args: StepperChangingEventArgs) {
  if (!isFormValid()) {
    args.cancel = true; // Prevent step change
  }
}

Use event handlers to track navigation and validate progress.
