Как можно контролировать выполнение анимаций?
У меня есть вот такой код

И мне нужно чтобы если я переключаю с menu_0 на menu_1 то вначале код должен скрыть menu_0 а после окончания анимаций включалась анимация появления menu_1 Примерно так
Но почему-то код устанавливает только одну анимацыю на одну кнопку и меняет виджеты как то хоатично. Можно ли это как то исправить?

Сделал изменения
- Добавил сохранение начальных позиций
menu, чтобы знать куда их возвращать - Сделал упорядочивание
menu, чтобы меню с_expand = Trueбыло первым, тогда при анимации оно сначала поедет, а после тот, чей radio-button возведен - Рефакторинг кода
