### Integration with Build Tools

**Webpack/Vite/Parcel**: The library works out-of-the-box with modern bundlers.

**CSS Framework Integration**: You can use the components with any CSS framework. The included CSS provides Material Design styling, but you can override it with your own styles.

**TypeScript**: Full TypeScript support with comprehensive type definitions included.

See the [live documentation](https://erikvullings.github.io/mithril-materialized/index.html) for examples and component APIs.

> **Note**: The date range picker is now fully implemented with comprehensive validation and formatting support.

## Build instructions

This repository consists of two packages, combined using `lerna`: the `lib` package that is published to `npm`, as well as an `example` project which uses this library to display the Mithril components that it contains.

To install the dependencies, you can use `npm i`, or, alternatively, use `pnpm m i` (assuming you have installed `pnpm` as alternative package manager using `npm i -g pnpm`) to perform a multi-repository install. Next, build everything using `npm start` and visit the documentation page on [http://localhost:1234](http://localhost:1234) in case port 1234 is not occupied already.

## 🎨 Styling & CSS

### CSS Usage

The library includes carefully crafted CSS that provides Material Design styling without external dependencies. You can import the ready-to-use CSS:

```typescript
import 'mithril-materialized/index.css';
```

**Important**: The CSS styling is **completely independent** of the original materialize-css. This means:

- ✅ No conflicting styles from materialize-css
- ✅ Smaller CSS bundle size
- ✅ Custom optimizations for better performance
- ✅ No external font dependencies

### 🔥 NEW: Modular CSS Architecture

**Tree-shakable CSS modules** for optimal bundle sizes! Import only the CSS you need:

```typescript
// Option 1: Import everything (64KB total)
import 'mithril-materialized/index.css';

// Option 2: Import only what you need (modular approach)
import 'mithril-materialized/core.css';      // Essential styles (18KB)
import 'mithril-materialized/forms.css';     // Form components only
import 'mithril-materialized/components.css'; // Interactive components

// Option 3: Advanced components only when needed
import 'mithril-materialized/pickers.css';   // Date/Time pickers
import 'mithril-materialized/advanced.css';  // Carousel, sidenav, etc.
import 'mithril-materialized/utilities.css'; // Badges, icons, cards
```

**CSS Modules Available:**

- `core.css` (18KB) - Essential foundation (normalize, grid, typography, variables)
- `components.css` - Interactive components (buttons, dropdowns, modals, tabs)
- `forms.css` - All form components (inputs, selects, switches, file upload)
- `pickers.css` - Date and time picker components
- `advanced.css` - Specialized components (carousel, sidenav, navbar, preloader)
- `utilities.css` - Visual utilities (badges, cards, icons, toast, chips)

**Bundle Size Optimization:**

- Full bundle: 64KB gzipped (44KB JS + 20KB CSS)
- Modular approach can reduce CSS by 30-50%
- Use only `core.css` + specific modules for your use case

### 🌓 Dark Theme Support

Built-in dark theme support with CSS custom properties:

```typescript
import { ThemeManager, ThemeSwitcher } from 'mithril-materialized';

// Programmatic theme control
ThemeManager.setTheme('dark');    // 'light' | 'dark' | 'auto'
ThemeManager.toggle();            // Toggle between light/dark
ThemeManager.getTheme();          // Get current theme

// UI Components
m(ThemeSwitcher, {
  onThemeChange: (theme) => console.log('Theme:', theme)
});

m(ThemeToggle); // Simple toggle button
```

**CSS Custom Properties**: All colors use CSS variables for runtime theme switching:

```css
:root {
  --mm-primary-color: #26a69a;
  --mm-background-color: #ffffff;
  --mm-text-primary: rgba(0, 0, 0, 0.87);
}

[data-theme="dark"] {
  --mm-primary-color: #80cbc4;
  --mm-background-color: #121212;
  --mm-text-primary: rgba(255, 255, 255, 0.87);
}
```

### SASS Usage

For advanced customization, you can use the SASS source files directly:

```css
// Import all SASS components
@import 'mithril-materialized/sass/materialize.scss';

// Or import individual components
@import 'mithril-materialized/sass/components/buttons';
@import 'mithril-materialized/sass/components/forms';
@import 'mithril-materialized/sass/components/grid';
```

**SASS Variables**: You can customize colors, spacing, and other design tokens by overriding SASS variables before importing:

```css
// Customize Material Design variables
$primary-color: #2196F3;
$secondary-color: #FF9800;

// Then import the library
@import 'mithril-materialized/sass/materialize.scss';
```

### Custom Styles

```css
/* For the switch */
.clear,
.clear-10,
.clear-15 {
  clear: both;
  /* overflow: hidden; Precaution pour IE 7 */
