Problem description

When using a Select, and passing an array of groups to options(), numeric keys (representing database IDs) are discarded when getting the enabled options via $component->getEnabledOptions().

public function getEnabledOptions(): array
{
    return collect($this->getOptions())
        ->reduce(function (Collection $carry, $label, $value): Collection {
            if (is_array($label)) {
                return $carry->merge($label); // <= this discards numeric keys
            }

            return $carry->put($value, $label);
        }, collect())
        ->filter(fn ($label, $value) => ! $this->isOptionDisabled($value, $label))
        ->all();
}

Expected behavior

Numeric keys are kept, flattening the options array like so:

public function getEnabledOptions(): array
{
    return collect($this->getOptions())
        ->reduce(function (Collection $carry, $label, $value): Collection {
            if (is_iterable($label)) {
                foreach ($label as $k => $v) {
                    $carry->put($k, $v);
                }

                return $carry;
            }

            return $carry->put($value, $label);
        }, collect())
        ->filter(fn ($label, $value) => ! $this->isOptionDisabled($value, $label))
        ->all();
}

Steps to reproduce

Having the following schema:

return $form->schema([
    Forms\Components\Select::make('foobar')
        ->options([
            'Foo' => [
                10 => 'Option 10',
            ],
            'Bar' => [
                20 => 'Option 20',
            ],
        ])
        ->in(function (Select $component): array {
            dd($component->getEnabledOptions());
        })
        ->required(),
]);

This is the result of the dd:

array:2 [▼ // app/Filament/Resources/PageResource.php:37
  0 => "Option 10"
  1 => "Option 20"
]

While I expected this result:

array:2 [▼ // app/Filament/Resources/PageResource.php:35
  10 => "Option 10"
  20 => "Option 20"
]
