layout of StringItem on Form

When more then one StringItem append on the form, Then some StringItem show on Form in Two coloums(First Lable and Textual data left side, Secound Lable and Textual data in right side. Like Show as Form divided in to Two coloums), and other StringItem again show proper on the Form. And some time next StringItem Lable start just after first Textual Data not from next line. For this implementation i use MIDP1.0 and append only StringItem on the Form.
Hint:- Maximum time this problem comes when i use for loop and Every time StringItem Lable and Textuale data length dynamic change.

Thanks
