}
```

## Usage

### Model Field

```
from chedito.fields import RichTextField

class Article(models.Model):
    # Basic usage
    content = RichTextField()

    # With custom configuration
    content = RichTextField(
        quill_config={
            'modules': {
                'toolbar': ['bold', 'italic', 'link']
            }
        }
    )
```

### Form Widget

from django import forms
from chedito.widgets import RichTextWidget

class ArticleForm(forms.Form):
    content = forms.CharField(widget=RichTextWidget())
```

```

### Standalone Editor

{% chedito_editor "content" initial_value %}
```

## Storage Backends

### Django Default Storage (default)

Uses Django's configured default storage backend:

```
CHEDITO_CONFIG = {
    'storage_backend': 'chedito.storage.default.DefaultStorage',
}
```

### Local Filesystem

```
CHEDITO_CONFIG = {
    'storage_backend': 'chedito.storage.local.LocalStorage',
}
```

### Custom Backend

Create your own storage backend:

```
from chedito.storage.base import BaseStorage

class MyCustomStorage(BaseStorage):
    def save(self, file, filename, upload_type='file'):
        # Save file and return URL
        pass

    def delete(self, filename):
        # Delete file
        pass

    def url(self, filename):
        # Return file URL
        pass

    def exists(self, filename):
        # Check if file exists
        pass
```

## Accessibility

Chedito is built with accessibility in mind and provides full screen reader support:

### Screen Reader Support

All toolbar controls are properly labeled for screen readers (NVDA, JAWS, VoiceOver):

- **Toolbar buttons**: Each button has descriptive `aria-label` (e.g., "Bold", "Italic", "Insert Image")
- **Toggle buttons**: Include `aria-pressed` state that updates when activated
- **Dropdown menus**: Properly labeled with `aria-haspopup`, `aria-expanded`, and `aria-label`
- **Dropdown options**: Each option has a descriptive label (e.g., "Heading 1", "Normal text", "Align Center")
- **Editor content area**: Marked as `role="textbox"` with `aria-multiline="true"`
- **Toolbar container**: Has `role="toolbar"` with descriptive label

### Keyboard Navigation

- Tab through toolbar controls
- Enter/Space to activate buttons
- Arrow or tab keys to navigate dropdown options

### Labels for All Controls

| Control | Label |
|---------|-------|
| Bold | "Bold" |
| Italic | "Italic" |
| Underline | "Underline" |
| Strikethrough | "Strikethrough" |
| Subscript | "Subscript" |
| Superscript | "Superscript" |
| Block Quote | "Block Quote" |
| Code Block | "Code Block" |
| Numbered List | "Numbered List" |
| Bulleted List | "Bulleted List" |
| Decrease Indent | "Decrease Indent" |
| Increase Indent | "Increase Indent" |
| Align buttons | "Align Left", "Align Center", "Align Right", "Justify" |
| Link | "Insert Link" |
| Image | "Insert Image" |
| Video | "Insert Video" |
| Clean | "Remove Formatting" |
| Heading dropdown | "Heading Style dropdown" |
| Color picker | "Text Color dropdown" |
| Background picker | "Background Color dropdown" |

## Security

### HTML Sanitization

Chedito sanitizes HTML content to prevent XSS attacks. Install a sanitization library:

```
pip install chedito[sanitize]  # Recommended: uses nh3
```

Configure allowed tags and attributes:

```
CHEDITO_CONFIG = {
    'sanitize_html': True,
    'allowed_tags': ['p', 'br', 'strong', 'em', 'a', 'img', ...],
    'allowed_attributes': {
        'a': ['href', 'title'],
        'img': ['src', 'alt'],
        ...
    },
}
```

### Upload Restrictions

```
CHEDITO_CONFIG = {
    'require_authentication': True,  # Require logged-in users
    'staff_only_uploads': True,      # Restrict to staff users
}
```

## Admin Integration

### Basic Integration

```
from chedito.admin import RichTextAdminMixin

@admin.register(Article)
class ArticleAdmin(RichTextAdminMixin, admin.ModelAdmin):
    pass
```

### With Inlines

```
from chedito.admin import RichTextStackedInline, RichTextTabularInline

class CommentInline(RichTextStackedInline):
    model = Comment
    extra = 1

@admin.register(Article)
class ArticleAdmin(RichTextAdminMixin, admin.ModelAdmin):
    inlines = [CommentInline]
```

### Custom Admin Configuration

```
@admin.register(Article)
class ArticleAdmin(RichTextAdminMixin, admin.ModelAdmin):
    chedito_config = {
        'modules': {
            'toolbar': ['bold', 'italic', 'link']
        }
