надеюсь, кто-то может помочь. У меня есть этот бесконечный массив, означающий, что я могу продолжать добавлять к нему детей. Я хочу отобразить в виде крошки следующим образом:
Категория 1> Sub Cat 1> и т. Д.> И т. Д.
Категория 1> Sub Cat 2> и т. Д.> И т. Д.
Категория 2> Sub Cat 1> и т. Д.> И т. Д.
Категория 2> Sub Cat 2> и т. Д.> И т. Д.
Это возможно с моей текущей структурой данных ?! Спасибо!

Как сказал Эстши, да, ты можешь это сделать.
Я позволил себе испытать это и смог решить вашу проблему.
