Öncelikle Selamun Aleyküm php bilmediğim için aklımda olan bileşenlerin özelliklerini birleştiremiyorum da yardımcı olurmusunuz
Kullanmak istediğim bileşen şu özelliği ise kategoriyi id ye göre listeliyor
Bu da bildiğimiz wordpress in kendisinde olan bileşen bundaki kullanmak istediğim özelliği işe dropdown yani açılır olarak göstermesi bu ikisini birleştiremedim bilenler için kolaydır ama bilmeyene gerçekten zor
Kullanmak istediğim bileşen şu özelliği ise kategoriyi id ye göre listeliyor
