Adam bir sorunla karşı karşıyayım. 2 boyutlu verilerim var. Verilerin bağlantılar içeren iç içe bir yapısı vardır.

Benim görevim, bu 2 boyutlu verileri kullanmak ve içinde reactpush panel benzeri bir yapıya sahip bir mobil menü oluşturmak .
Yine de böyle yaratmaya çalışıyorum. Yaptığım her alt diziye ayrı bir panel olarak işlem yapmaktı div. İlk olarak, varsayılan olarak görünen kök panelde alt dizi öğeleri dikkate alınacaktır. Bir öğenin bir childrenözelliği varsa next, o liste öğesinde dinamik bir düğme oluşturulduğu anlamına gelir . Bu düğmeye tıkladığımızda is-visible, panele bir sınıf ekleyecektir . Ancak, soru, bu panel tıklamasıyla hangi panelin ilişkili olduğunu nasıl izleyeceğidir ? Bir durum kullanmaya çalışıyorum activeIdve prevIdAma dizinlemem düzgün çalışmıyor ve doğru bir panel açmıyor. Çözümümü krom denetçisi panelinden inceleyebilirsiniz. Bana neyi yanlış yaptığımı söylesen çok memnun olurum?
