Açıklama

Varsayılan sağ tıklama menüsünü (bağlam menüsü) geçersiz kılan ve özel tasarlanmış bir menü görüntüleyen bir kullanıcı arayüzü pasajı.

Özellikler

• ‘contextmenu’ olayını bağlayarak varsayılan menüyü gizleyin
• Menülerin ekranın kenarında kesilmesini önlemek için otomatik konum ayarı
• Cammorfizmi birleştiren modern tasarım
• Animasyonla sorunsuz açılma ve kapanma
• Menüyü harici tıklama veya ‘Escape’ tuşuyla gizleyin

Uygulama noktaları

Konum hesaplamasında getBoundingClientRect() kullanarak ve tarayıcı penceresi boyutu ile tıklanan koordinatları karşılaştırarak menüyü ekrandan dışarı taşmayacak şekilde kontrol ediyoruz.
