Adjusting repeater select box values dynamically

Figured out the solution, I'm not sure if it's the best way to do it but it's the way I've done it

        Repeater::make('countries_worked_in')
                    ->schema([
                        Select::make('continent')
                            ->options(array_map(fn ($continent) => $continent['name'], World::continents()->toArray()))
                            ->required()
                            ->live(),
                        Select::make('country')
                            ->options(function(Get $get){
                                if (!$get('continent')) {
                                    return [];
                                }
                                $countries = [];
                                foreach (World::Countries() as $country) {
                                    if ($country->continent_id == $get('continent')+1) {
                                        $countries[$country->name] = $country->name;
                                    }
                                }
                                return $countries;
                            })
                            ->required(),
                    ]),

        Repeater::make('countries_worked_in')
                    ->schema([
                        Select::make('continent')
                            ->options(array_map(fn ($continent) => $continent['name'], World::continents()->toArray()))
                            ->required()
                            ->live(),
                        Select::make('country')
                            ->options(function(Get $get){
                                if (!$get('continent')) {
                                    return [];
                                }
                                $countries = [];
                                foreach (World::Countries() as $country) {
                                    if ($country->continent_id == $get('continent')+1) {
                                        $countries[$country->name] = $country->name;
                                    }
                                }
                                return $countries;
                            })
                            ->required(),
                    ]),

Setting a component to live makes the entire form refresh (without losing data). You can then use what I've done in the options field in using a callback with the Get parameter to pull the data from the first field to use in the next after the refresh
