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.
