Installation

You can install the package in to a Laravel app that uses Nova via composer:

composer require lupennat/preview

Usage

Preview Field can be used to Display a Detail Field on Index Page in a dropdown (like Nova BooleanGroup Field Behaviour). On Detail Page, the field will be always displayed as native field, on Form pages the Field will not be displayed.

When Method

You can use when method to switch between preview/inline mode at specific condition.
If a string will be returned from callback, the string will be used as text for the dropdown button.

use Illuminate\Support\Str;
use Laravel\Nova\Fields\Text;
use Laravel\Nova\Http\Requests\NovaRequest;
use Lupennat\Preview\Preview;

class Post extends Resource
{

    public function fields(Request $request)
    {
        return [
            Preview::make(__('Title'), 'title')->when(
                fn($value, $resource, $attribute) => strlen($value) > 20 ? Str::limit($value, 20) : false,
                Text::make(__('Title'), 'title')
            )
        ];
    }
}

Is Method

You can use is method to always display a field as preview.

use Laravel\Nova\Fields\Text;
use Laravel\Nova\Http\Requests\NovaRequest;
use Lupennat\Preview\Preview;

class Post extends Resource
{

    public function fields(Request $request)
    {
        return [
            Preview::make(__('Description'), 'description')
                ->is(Text::make(__('Description'), 'description'))
                ->withPreviewLabel(__('View Description'))
        ];
    }
}
