UNHIDABLE attribute
The UNHIDABLE attribute indicates that the element cannot be hidden
or shown by the user with the context menu.
Syntax
UNHIDABLEUsage
By default, a TABLE or TREE container allows the user to
hide the columns by a right-click on the column header.
Use the UNHIDABLE attribute to prevent the user from hiding a specific
column.
The end user is also not allowed to show columns that are hidden by default with
HIDDEN=USER.
Makes sense only for a field that is used for the definition of a column in a
TABLE or TREE container.
Example
EDIT c01 = item.comment, UNHIDABLE;
