Adding different pivotData in N:N relationship

My Property and PropertyFeature has N:N relationship. And I have additional pivot table fields ( ‘number’, ‘max number’, and ‘selected_types’ as a json field).

PropertyFeature has feature 'name' and 'type' field as json. In my pivot table I want to multi-select the json data based on the available options from json 'type' field data in PropertyFeature. This i want to do while creating Property Record. I have so far below code in my Property resource file.

Forms\Components\Select::make('property_type_id')
    ->relationship(name: 'propertyType', titleAttribute: 'name', modifyQueryUsing: function (Builder $query, Get $get) {
        $query->whereHas('propertyCategories', function ($q) use ($get) {
            $q->where('property_category_id', $get('property_category_id'));
        });
    })
    ->searchable()
    ->preload()
    ->live()
    ->afterStateUpdated(function (Set $set) {
        $set('propertyAmenities', null);
    })
    ->required(),

Forms\Components\Select::make('propertyTypeFeatures')
    ->multiple()
    ->relationship(titleAttribute: 'name', modifyQueryUsing: function (Builder $query, Get $get) {
        $query->whereHas('propertyTypes', function ($q) use ($get) {
            $q->where('property_type_id', $get('property_type_id'));
        });
    })
    ->searchable()
    ->preload()
    ->required(),


What approach I should take for making entry in pivot table for each selected PropertyTypeFeatures. And how?
Solution
I used below code to solve my challenge. I used repeater in BelongsToMany relationship and used dependent select.

Forms\Components\Select::make('property_type_id')
    ->relationship(name: 'propertyType', titleAttribute: 'name', modifyQueryUsing: function (Builder $query, Get $get) {
        $query->whereHas('propertyCategories', function ($q) use ($get) {
            $q->where('property_category_id', $get('property_category_id'));
        });
    })
    ->searchable()
    ->preload()
    ->live()
    ->afterStateUpdated(function (Set $set) {
        $set('propertyAmenities', null);
    })
    ->required(),


Forms\Components\Repeater::make('propertyPropertyTypeFeatures')
    ->relationship()
    ->schema([
        Forms\Components\Select::make('property_type_feature_id')
            ->relationship('propertyTypeFeature', 'name', modifyQueryUsing: function (Builder $query, Get $get) {
                $query->whereHas('propertyTypes', function ($q) use ($get) {
                    $q->where('property_type_id', $get('../../property_type_id'));
                    // $q->where('property_type_id', 1);
                });
            })
            ->live()
            ->afterStateUpdated(function (Set $set) {
                $set('selected_feature_types', null);
            })
            ->required(),

        Forms\Components\TextInput::make('number')
            ->integer(),

        Forms\Components\TextInput::make('max_number')
            ->integer(),

        Forms\Components\Select::make('selected_feature_types')
            ->multiple()
            ->options(function (callable $get){
                $selectOptions = PropertyTypeFeature::find($get('property_type_feature_id'));
                if($selectOptions){
                    return $selectOptions->available_feature_type;
                }
                return null;
            })
            ->preload()
            ->searchable(),
        ]),
