How to make a rule "in" of a multiple select

I have the following code:

Select::make('middlewares')
    ->translateLabel()
    ->required()
    ->multiple()
    ->default(['web'])
    ->options([
        'web' => 'web',
        'auth' => 'auth',
        'guest' => 'guest',
        'signed' => 'signed'
    ])->in('web,auth,guest,signed'),

Select::make('middlewares')
    ->translateLabel()
    ->required()
    ->multiple()
    ->default(['web'])
    ->options([
        'web' => 'web',
        'auth' => 'auth',
        'guest' => 'guest',
        'signed' => 'signed'
    ])->in('web,auth,guest,signed'),

When I submit the form I get the error: The middlewares field is not in the list of allowed values. In Laravel, to validate an array, you use middlewares.*, but I don't know how to do it in filament

Did you try an actual array? Not a comma separated string

->in(['web', 'auth', 'guest', 'signed'])

->in(['web', 'auth', 'guest', 'signed'])

It works if the multiple is removed, but when adding the multiple it gives me that error

Ah. Makes sense, because it's an array. Maybe that's a bug

In Laravel, if it is a validation of an array, the field.* is used, but if filament does not support this, I will have to do a manual validation

->rule(fn (Select $component) => function (string $attribute, $value, Closure $fail) use($component){
    $in = ['web', 'auth', 'guest', 'signed'];
    foreach ($value as $tmp) {
        if (!in_array($tmp, $in)) {
            $fail(__('validation.in', ['attribute' => $component->getLabel()]));
        }
    }
})

->rule(fn (Select $component) => function (string $attribute, $value, Closure $fail) use($component){
    $in = ['web', 'auth', 'guest', 'signed'];
    foreach ($value as $tmp) {
        if (!in_array($tmp, $in)) {
            $fail(__('validation.in', ['attribute' => $component->getLabel()]));
        }
    }
})

actually, dont we have nestedRecursiveRules() for this?

I think the filament doesn't have support for this case, I also tried with

->validationAttribute('middlewares.*')

->validationAttribute('middlewares.*')

but it doesn't work
