#Single Select Filter

Every Select filter needs to have the options method that return a value and text. It also needs a type property $type which needs to be set as single-select.

<?php

namespace App\Laracube\Filters;

use App\Models\User;
use Laracube\Laracube\Base\Filter;

class UserFilter extends Filter
{
    /**
     * The single value that will be displayed as heading.
     *
     * @var string
     */
    public $heading = 'Select User';

    /**
     * The single value that will be used as request key.
     *
     * @var string
     */
    public $key = 'user_id';

    /**
     * The type of the filter.
     *
     * @var string
     */
    public static $type = 'single-select';

    /**
     * Get the options for the filter.
     *
     * @return mixed
     */
    public function options()
    {
        return User::orderBy('name')
            ->selectRaw('id AS value, name AS text')
            ->get();
    }
}

    public static $type = 'multiple-select';

    /**
     * Get the options for the filter.
     *
     * @return mixed
