Re: Best practice add optional="show" when adding fields in tree viewsby

Sorry, my bad. I don't know why, I read optional="hide". It's OK to put optional="show", but I would leave out of the equation mandatory fields without default, or those protected with a group, as the group is already the filtering method for not showing them.
