When to Use This Skill

Use the Syncfusion TypeScript Stepper skill when you need to:

• Display a multi-step process or wizard workflow
• Create a progress indicator showing completion status
• Build a form wizard with validation between steps
• Show step-by-step guided experiences (checkout, onboarding, setup)
• Add step navigation with back/forward controls
• Implement linear workflow validation
• Create checkpoint-based processes with tracking
• Enable step customization with icons, labels, and templates
• Handle step events and user interactions
• Support multiple orientations (horizontal/vertical layouts)

Stepper Overview

The Stepper is a navigation control that displays a series of logical steps to guide users through a workflow. Each step can have:

• Indicators (numbers, icons, or shapes)
• Labels (text descriptions)
• Status tracking (active, completed, disabled)
• Event handlers for step transitions
• Custom templates for rich content
• Flexible styling with themes

Key Characteristics

Aspect	Description
Component	Navigation control for multi-step workflows
Steps	Array of step objects with properties
Indicators	Numbered or icon-based step markers
Orientations	Horizontal (default) or Vertical layouts
Types	Default (icon+label), Label-only, Indicator-only
Events	created, beforeStepRender, stepClick, stepChanging, stepChanged
Methods	12 control methods (nextStep, previousStep, reset, etc.)
Properties	15 stepper + 8 step properties
Customization	Templates, animations, themes, CSS styling

📚 Learning Path (Recommended Order)

1. Start Here: Getting Started

   • Installation and npm package setup
   • Dependencies (ej2-navigations, ej2-base, ej2-popups)
   • Development environment configuration
   • Basic stepper initialization with code examples
   • CSS imports and theme setup

2. Fundamentals: Steps Configuration

   • Adding steps to the stepper
   • Step properties (iconCss, text, label, cssClass, disabled, status)
   • Using StepModel interface for type safety
   • Step arrays and dynamic step updates
   • Accessing and modifying steps at runtime

3. Data Organization: Step Types

   • Default type: icons with labels
   • Label-only type: text descriptions only
   • Indicator-only type: numbers or icons only
   • Label positions (top, bottom, start, end)
   • Choosing the right type for your use case

4. UI Layout: Orientations and Layout

   • Horizontal orientation (default, side-by-side)
   • Vertical orientation (stacked, one above another)
   • Responsive behavior and switching
   • Layout-specific styling

5. Interactivity: Events and Interaction

   • stepChanged: when step successfully changes
   • stepChanging: before step change (can cancel)
   • stepClick: user clicked a step
   • beforeStepRender: before rendering each step
   • created: initialization complete
   • Event arguments and patterns

6. Enhancements: Templates and Animation

   • Custom HTML templates for step content
   • Template data binding

Quick Start Example

Here's a minimal stepper setup to get started immediately:

import { Stepper } from '@syncfusion/ej2-navigations';

// Create a basic stepper with 4 steps
let stepper: Stepper = new Stepper({
  steps: [
    { label: 'Cart' },
    { label: 'Shipping' },
    { label: 'Payment' },
    { label: 'Confirmation' }
  ]
});

// Render to DOM
stepper.appendTo('#stepper');

<nav id="stepper"></nav>

Common Patterns

Pattern 1: Icon + Label Steps (Default)

import { Stepper, StepModel } from '@syncfusion/ej2-navigations';

let steps: StepModel[] = [
  { iconCss: 'sf-icon-cart', label: 'Cart' },
  { iconCss: 'sf-icon-truck', label: 'Shipping' },
  { iconCss: 'sf-icon-payment', label: 'Payment' }
];

let stepper: Stepper = new Stepper({ steps: steps });
stepper.appendTo('#stepper');

Pattern 2: Vertical Workflow with Events

import { Stepper } from '@syncfusion/ej2-navigations';

let stepper: Stepper = new Stepper({
  steps: [{}, {}, {}, {}],
  orientation: 'Vertical',
  stepChanged: (args) => console.log('Changed to step:', args.activeStep),
  stepChanging: (args) => {
    if (!validateCurrentStep()) args.cancel = true;
  }
});
stepper.appendTo('#stepper');

Pattern 3: Form Wizard with Validation

import { Stepper, StepperChangingEventArgs } from '@syncfusion/ej2-navigations';

let stepper: Stepper = new Stepper({
  steps: [
    { label: 'Personal Info' },
    { label: 'Address' },
    { label: 'Review' }
  ],
  linear: true,  // Must complete steps in order
  stepChanging: (args: StepperChangingEventArgs) => {
    // Validate current step before allowing transition
    if (!isCurrentStepValid()) {
      args.cancel = true;  // Prevent step change
    }
  }
});
stepper.appendTo('#stepper');

Pattern 4: Dynamic Step Management

import { Stepper } from '@syncfusion/ej2-navigations';

let stepper: Stepper = new Stepper({
  steps: [{}, {}, {}, {}],
  activeStep: 0
});
stepper.appendTo('#stepper');

// Navigate with methods
stepper.nextStep();      // Move to next step
stepper.previousStep();  // Move to previous step
stepper.reset();         // Return to first step

// Update properties
stepper.activeStep = 2;
stepper.dataBind();      // Apply changes
