If my requirement is to update/delete the data in the entities from the UI screen, how should i handle it in preparation? Any existing application flow or code to handle is appreciated.



You could use the editable table.

I would not recommend building a table with input fields (dropdowns make it insanely slow).
The best you could do is to use the scaffold editable screens you learn in the tutorial lessons, this keeps the pages seperated and fast. If you still wish to continue, the editable table is your best option, though it is not recommended to use for tons of rows.
