WordPress her kategori için custom bir alan nasıl oluşturulur?

turansonkaya adlı üyeden alıntı: mesajı görüntüle

Selamlar,
WordPress üzerinde her ürün kategorisi için custom bir alan yaratıp kategorinin en altına sabitlemek istiyorum.
Her kategori için farklı açıklamalar olacak.
Bahsettiğim alan kategori içinde bulunan "Kategori Açıklaması" harici olacak şekilde bir yeni alan yaratmak istiyorum.
Bunu yapabileceğim bir eklenti var mıdır?
