Customization

The stepper component can be customized using CSS variables and by providing custom templates for navigation and buttons.

CSS Variables

:root {
  --stepper-direction: column;
  --stepper-primary-color: #009ef7;
  --stepper-secondary-color: #b5b5c3;
  --stepper-background-color: #f3f6f9;
  --stepper-text-color: #181c32;
  --stepper-disabled-color: #e1e3ea;
}

Programmatic Customization

You can also customize the stepper appearance programmatically using the StepperThemeService:

import { StepperThemeService } from '@hub-ui/stepper';

@Component({...})
export class YourComponent implements OnInit {
  constructor(private themeService: StepperThemeService) {}

  ngOnInit() {
    this.themeService.setTheme({
      'primary-color': '#ff4081',
      'background-color': '#f0f0f0'
    });
  }
}

This allows you to change the theme dynamically based on user preferences or other conditions in your application.

Custom Navigation Buttons

You can customize the navigation buttons using the provided directives:

<hub-stepper>
  <!-- Step content -->
  <button previousButton>Custom Back</button>
  <button nextButton>Custom Next</button>
  <button submitButton>Custom Submit</button>
</hub-stepper>

These directives (previousButton, nextButton, and submitButton) automatically handle the navigation logic and apply default styling classes.

Custom Navigation Template

<hub-stepper [stepperNavTpt]="customNavTemplate">
  <!-- step content -->
</hub-stepper>

<ng-template #customNavTemplate let-steps="steps" let-currentIndex="currentIndex">
  <!-- Your custom navigation markup -->
</ng-template>

Examples

Basic Usage

<hub-stepper>
  <hub-step title="Personal Info">
	<!-- Personal info form fields -->
  </hub-step>
  <hub-step title="Address">
	<!-- Address form fields -->
  </hub-step>
  <hub-step title="Confirmation">
	<!-- Confirmation step -->
  </hub-step>
</hub-stepper>

With Custom Navigation

<hub-stepper [stepperNavTpt]="customNav">
  <!-- Steps content -->
</hub-stepper>

<ng-template #customNav let-steps="steps" let-currentIndex="currentIndex">
  <ul class="custom-nav">
	<li *ngFor="let step of steps; let i = index"
		[class.active]="i === currentIndex">
	  {{ step.title }}
	</li>
  </ul>
</ng-template>

Inspiration

This project was inspired by the need for a flexible, customizable, and accessible stepper component in the Angular ecosystem. We drew inspiration from:

• Material Design's Stepper component
• Various multi-step form implementations across the web
• Feedback and feature requests from the Angular community

My goal was to create a component that combined the best features of existing solutions while adding my own improvements and focusing on customization and accessibility.
