IsVisible
IsVisible specifies whether the field or checkbox is visible.

e.g. In case you don't need FCP projects, you can set IsVisible to FALSE to hide the control in the user interface.

Be sure not to set inconsistent setting, e.g. IsVisible = FALSE, Default = FALSE and IsMandatory = TRUE

Possible values: 1, TRUE, YES, 0, FALSE, NO
Default value: 1
