jadi di project ini user bertindak sebagai kasir untuk menghitung jumlah item yang dibeli customer. problemnya adalah dynamic input ini bisa bekerja secara sempurna. namun untuk pencarian data produk dan menampilkan field yang sesuai di text field pada form di field yang append tidak bekerja. saya mau tanya ini penyebabnya apa. dan bagaimana solusinya. Terima Kasih ------------------------- View --------------------
