Я внедрил навигационное меню superfish в установку umbraco. Superfish просто берет элемент UL и превращает его в иерархическое меню, которое показывает дочерние элементы, когда вы наводите курсор на родительский элемент (вы помните, когда они были крутыми в 1999 году, верно?).
Я не могу понять, почему на некоторых страницах (обычно без детей) в меню не отображаются дочерние элементы для какой-либо страницы. Мое знакомство с XSLT минимально, поэтому я не обращаю внимания на некоторую логику.
Здесь вы можете увидеть реальный сайт здесь Наведите курсор на «персональную тренировку», чтобы увидеть работу меню, теперь нажмите «Управление весом» и, эй-престо, волшебство перестает происходить.
XSLT, создающий структуру UL, приведен ниже, а источник HTML-страницы сообщает мне, что при возникновении проблемы просто не генерируется никаких элементов LI для дочерних страниц.
