Why does deleting a React list row move another row’s input value?
KitForma editorial guide. An index key identifies a position, so deleting a row can associate an existing input with a different record.
Step-by-step guidance
An index key identifies a position, so deleting a row can associate an existing input with a different record. Use the record’s stable identifier:
rows.map(row => <Editor key={row.id} row={row} />). Generate IDs when creating records, never during rendering. Test editing the second row, deleting the first and sorting. Keys need uniqueness among siblings; they do not automatically become an id prop.Sources and verification
