Changing Field Widths
To change the width of an object type field:
From the Workbench shortcut bar, select Deployment Mgmt > Object Types.
The Object Type Workbench opens.
Open an object type.
The Object Type window opens.
Click the Layout tab.
Select a field.
In the Field Width field, select 1 or 2.
The Layout editor does not let you make changes that conflict with another field in the layout. For fields of component type Text Area, you can determine the number of lines the text area displays by clicking the Text Area type field and changing the value in the Component Lines attribute. If the selected field is not of type Text Area, this attribute is blank and cannot be changed.
