#Installation

Install the package in a Laravel Nova project via Composer:

composer require outl1ne/nova-multiselect-filter

#Usage

The filter can be used when switching Filter class with MultiselectFilter.

use Outl1ne\NovaMultiselectFilter\MultiselectFilter;
 
class BooksByAuthorFilter extends MultiselectFilter
{
    public function apply(Request $request, $query, $value)
    {
        return $query->whereHas('books', function ($query) use ($value) {
            $query->whereIn('author_id', $value);
        });
    }
 
    public function options(Request $request)
    {
        return Authors::all()->pluck('name', 'id');
    }
}

#Option groups

Option groups are supported. Their syntax is the same as Laravel's option group syntax.

In this example (from Nova docs), all values are grouped by the group key:

public function options(Request $request)
{
    return [
      'cat' => ['label' => 'Cat', 'group' => 'Pets'],
      'dog' => ['label' => 'Dog', 'group' => 'Pets'],
      'eagle' => ['label' => 'Eagle', 'group' => 'Birds'],
      'parrot' => ['label' => 'Parrot', 'group' => 'Birds'],
    ]
}

#Options

Possible options you can pass to the filter using the option name as a function, ie ->placeholder('Choose peanuts').

#Localization

The translations file can be published by using the following publish command:

php artisan vendor:publish --provider="Outl1ne\NovaMultiselectFilter\FieldServiceProvider" --tag="translations"

You can then edit the strings to your liking.
