I have a multi-column layout, and have added a group box around 3 attributes. I would like to adjust the width and height of the box that surrounds the attributes in the box, as the column is running into the next column (area shaded yellow that is the dividing lines between the 2 columns).
Although there are height and width inputs for the group box, they only apply to the attributes inside the box, and not the box itself.
How can I shrink the size of the drawn box?
