## Styling

Autocomplete wraps a **daisyUI Input component** internally. All Input styling classes work:

| Category | Keywords                                                                                                                         | Description           |
| :------- | :------------------------------------------------------------------------------------------------------------------------------- | :-------------------- |
| Color    | `input-primary`, `input-secondary`, `input-accent`, `input-ghost`, `input-info`, `input-success`, `input-warning`, `input-error` | Input color variants  |
| Size     | `input-xs`, `input-sm`, `input-md`, `input-lg`                                                                                   | Input scale           |
| Style    | `input-bordered` (default), `input-ghost`                                                                                        | Visual style variants |
