## Assets

You can inject custom CSS or JS.

**ATTENTION**, if you are using this bundle inside a project with turbo, you might encounter race condition loading, it is recommended to inject directly in your project.

```php
'quill_extra_options' => [
   'assets' => [
       'styleSheets' => [
           "https://example.com/custom.css",
       ],
       'scripts' => [
           "https://example.com/custom.js",
       ]
   ],
]
```

## Custom Icons

Replace toolbar icons with your own SVGs.

```php
'quill_extra_options' => [
    'custom_icons' => [
        'bold' => '<svg ...>...</svg>',
        'italic' => '<svg ...>...</svg>',
    ]
],
```
