Share state between nested modal

    ->collapsible()
    ->schema([
        Forms\Components\Hidden::make('heading.color'), // sadly I need to have this, otherwise $set('heading.color', $data['color']); would be inside child modal only
        Forms\Components\TextInput::make("heading.text")
            ->hiddenLabel()
            ->required()
            ->columnSpan(5),
