Drop down in Straight Table

[krishnacbe]

Hi

I am having a Customer Name field in a straight table. I need to show only the customers in the straight table in Drop down list(as in Excel).

Example

Customer Name: A, B, C, D are in DB

Customer Name in Straight Table: A & B

Drop Down List : A,B,C,D  are viewed.

I need to display only A & B.

Thanks in Advance.
