Extra choice visibility options - Open when blank, hidden when populated

[Raymond Geerts]

Comonly i create list > item template combinations.

Like agenda list containing agenda items as children, or a news list containing news items.

Now in most cases the list templates title would be set once (Agenda / News) and after that does not have to be editable (or my wish to be hidden).

For that it would be nice to have an extra choice in the field visibility settings:

Open when blank, hidden when populated

So that while creating the page, the developer can set the title whichafter it wont be shown anymore, thus not being able to modify it.

I can do this manualy, create all the list pages and then modify the template setting the title field to hidden for the specific fieldgroup.
