Можно ли как нибудь сделать реактивное обновление и отображение данных и отображение данных в зависимости от условий полученных после извлечения этих данных из локального хранилища динамически?
Я тут попытался это сделать - получился небольшой франкенштейн из 2 параметров.

Здесь самая главная загвоздка в том что тут используются 2 параметра - showChildrenFlagProperty и showChildrenFlag.
