Validate multiple dynamic fields

hey there. I need to validate muliple dynamic fields in a special way. if you look at the screenshot you see some checkboxes. for each checked checkbox a new field apears. all fields together, summed up, must be 100. how can I validate this?

this is how I generatet the fields:

Forms\Components\CheckboxList::make('materials')
    ->label(false)
    ->gridDirection('row')
    ->columns(2)
    ->bulkToggleable()
    ->required()
    ->live()
    ->relationship('materials', 'name', modifyQueryUsing: fn (Builder $query) => $query->orderBy('id')),
Forms\Components\Fieldset::make(__('backend.materials.fields.plural_share'))
    ->visible(function(Forms\Get $get) {
        return $get('materials');
    })
    ->schema(function(Forms\Get $get) {
        $fields = [];
        if($get('materials')) {
            $materials = Material::whereIn('id',$get('materials'))->pluck('name','id')->toArray();
            foreach($get('materials') as $material) {
                $fields[] = TextInput::make('material_'.$material)
                    ->label($materials[$material])
                    ->required()
                    ->suffix('%')
                    ->numeric()
                    ->minValue(1)
                    ->maxValue(100);
            }
        }
        return $fields;
    }),

Forms\Components\CheckboxList::make('materials')
    ->label(false)
    ->gridDirection('row')
    ->columns(2)
    ->bulkToggleable()
    ->required()
    ->live()

Forms\Components\Fieldset::make(__('backend.materials.fields.plural_share'))
    ->visible(function(Forms\Get $get) {
        return $get('materials');
    })
    ->schema(function(Forms\Get $get) {
        $fields = [];
        if($get('materials')) {
            $materials = Material::whereIn('id',$get('materials'))->pluck('name','id')->toArray();
            foreach($get('materials') as $material) {

                    ->label($materials[$material])
                    ->required()

                    ->minValue(1)
                    ->maxValue(100);
            }
        }
        return $fields;
    }),

Hi there... you could use something like this?

Forms\Components\CheckboxList::make('materials')
    ->label(false)
    ->gridDirection('row')
    ->columns(2)
    ->bulkToggleable()
    ->required()
    ->live()
    ->options([1 => 'material 1', 2 => 'material 2', 3 => 'material 3']),
Forms\Components\Fieldset::make('percentages')
    ->visible(function(Forms\Get $get) {
        return $get('materials');
    })
    ->schema(function(Forms\Get $get) {
        $fields = [];
        if($get('materials')) {
            foreach($get('materials') as $material) {
                $fields[] = TextInput::make('material_'.$material)
