Conditional Filtering

Im assuming this is possible with custom functionality, but just wanted to check prior if there is any easy/simple solutions. I have a select filter based on a location state, but when I select a state, I want to then show another select with all cities under that state (and stay hidden if none exist).

This is what I have so far

                Filter::make('location')
                    ->form([
                        Select::make('state')
                            ->options(Location::all()->pluck('state', 'state')),
                        Select::make('city')
                            ->options(
                                Location::all()->pluck('city', 'city'),
                            )
                            ->hiddenOn('state', null),
                        // ->query(function (Builder $query, $state) {
                        //     if ($state['value'] == null) {
                        //         return $query;
                        //     } else {
                        //         return $query->whereHas('location', function ($q) use ($state) {
                        //             return $q->where('state', $state['value']);
                        //         });
                        //     }
                        // }),
                    ])
                    ->query(function (Builder $query, array $data): Builder {
                        return $query
                            ->when(
                                $data['state'],
                                fn (Builder $query, $state) => $query->whereHas('location', fn (Builder $query) => $query->where('state', $state))
                            )
                            ->when(
                                $data['city'],
                                fn (Builder $query, $city) => $query->whereHas('location', fn (Builder $query) => $query->where('city', $city))
                            );
                    }),

                Filter::make('location')
                    ->form([
                        Select::make('state')
                            ->options(Location::all()->pluck('state', 'state')),
                        Select::make('city')
                            ->options(
                                Location::all()->pluck('city', 'city'),
                            )
                            ->hiddenOn('state', null),
                        // ->query(function (Builder $query, $state) {
                        //     if ($state['value'] == null) {
                        //         return $query;
                        //     } else {
                        //         return $query->whereHas('location', function ($q) use ($state) {
                        //             return $q->where('state', $state['value']);
                        //         });
                        //     }
                        // }),
                    ])
                    ->query(function (Builder $query, array $data): Builder {
                        return $query
                            ->when(
                                $data['state'],
                                fn (Builder $query, $state) => $query->whereHas('location', fn (Builder $query) => $query->where('state', $state))
                            )
                            ->when(
                                $data['city'],
                                fn (Builder $query, $city) => $query->whereHas('location', fn (Builder $query) => $query->where('city', $city))
                            );
                    }),

I need the second select to hide when state is null, but also need to make the option in the second select filter depending on the value of the first select.

7 Filament Dependant Select Options - FilamentPHP V3 Tutorial

In this video, we will learn how to create dependant select options in FilamentPHP V3. We will start by creating a simple form with three select inputs, one for countries, one for states and one for cities. Then, we will use the $get() to make the state select input dependent on the country select input. This means that the options in the state...
