Matrix Field Properties
You can set the following properties for matrix fields:
Default Child Gravity
Selects the position of each simple field relative to its cell in a matrix field
Child Margin
Sets the distance (in 1000ths of an inch) between the individual matrix field components and the Left, Right, Top, or Bottom boundary of the matrix field
Collapse Policy
Specifies what happens when an entire row or column in the matrix is empty. Valid options are:
NONE
Specifies that empty rows and columns are allowed and maintained. If you set the Rows and Columns properties, the settings are enforced.
BOTH
Specifies that empty rows and columns are removed automatically, as soon as the last field is removed from the row or column. Setting either the Rows or Columns property has no effect.
EMPTY ROWS
Specifies that empty rows are removed automatically, as soon as the last field in the row is removed. Setting the Rows property has no effect. However, empty columns are maintained, and the Columns property is enforced.
EMPTY COLUMNS
Specifies that empty columns are removed automatically, as soon as the last field in the column is removed. Setting the Columns property has no effect. However, empty rows are maintained, and you can set the Rows property.
Default: BOTH
Rotation
Defines the desired rotation in degrees. This setting overrides any child field setting. Changes to rotation appear only after the report is run.
Note: If any grouped fields overlap other fields, use the Cut and Paste toolbar buttons to move fields around so they do not block other fields.
