The WANTFIXEDPAGESIZE attribute controls the vertical resizing of a list element.
WANTFIXEDPAGESIZE [ = NO ]
The WANTFIXEDPAGESIZE attribute can be used for TABLE and SCROLLGRID containers to control the vertical resizing of the list element.
By default, a TABLE container is resizable (vertically and horizontally). To freeze the height of the table to the number of lines defined by the form file, use the attribute WANTFIXEDPAGESIZE.
By default, a SCROLLGRID container is not resizable in height. The number of visible scrollgrid rows is defined by the form file. To allow the scrollgrid to stretch vertically, use the attribute WANTFIXEDPAGESIZE=NO.
