Question regarding Master Detail Layout Setup

Hello Everyone, I am have created a master detail page. I wanted to display details columns in vertical arrangement as shown in the attached pic. I am doing this to save the utilize the space available since I have a lot of columns (approx 120+) to be displayed.  I copied the built-in master detail column and created a new one to have columns displayed in parallel view instead of displaying these in single column. Mendix doesn’t give any error to me. But upon execution the layout gets distorted like below.   Could you anyone please suggest how to fix this problem? Regards, Puneet
