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').

Option	type	default	description
options	Array|callable	[]	Options in an array as key-value pairs (['id' => 'value']).
placeholder	String	Field name	The placeholder string for the input.
max	Number	Infinite	The maximum number of options a user can select.
groupSelect	Boolean	false	For use with option groups - allows the user to select whole groups at once
singleSelect	Boolean	false	Makes the field act as a single select. The returned value will be an array with one element.
optionsLimit	Number	1000	The maximum number of options displayed at once. Other options are still accessible through searching.

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.
