How can we help you?

I have a form for let's say a house.
All the data for that house is in a single JSON. So, no eloquent relationship.
The form has a repeater for each of the rooms.

Is it possible to filter which rooms are shown in the repeater?
E.g. only show the rooms of type: bedroom.

I may have found a solution, but feedback is welcome.

Forms\Components\Repeater::make('rooms')
    ->afterStateHydrated(fn($component, $state) => $component->state(
        collect($state)
            ->where('type', 'bedroom')
            ->values()
            ->toArray()
        )
    )
    ->schema([...])

Hello,
my feedback is that it does work but in a destructive way. For example, adding a second repeater with a different filter (es: type=suite) it will filter items of both the first and second repeater by type=suite, ending with the same values.
Hope its helpful to someone to save some time :)

I had the same problem today, and found another, potentially better, solution.
You can use the relationship function of Repeater to modify the query fetching relationships.

Here is an example from my project where I need to filter based on an enum of types.

Repeater::make('quiz_grades')
                    ->relationship('grades', fn (Builder $query) => $query->where('type', GradeType::Quiz))

In your case, I believe something like this should work:

Repeater::make('bedrooms')
    ->relationship('rooms', fn (Builder $query) => $query->where('type', 'bedroom'))
