Help index


The information below shows information for developers and is not meant for users or content providers. It describes the way properties are defined, information for lay-out or maintenance is provided, and information about imports are kept.

Item propertie are properties that are part of an item, but not visible for users. You can recognise them on a red frame around the property.They support developers or content maintainers to define lay-out, to improve functionality or to keep track of what needs to be done.

In the property page, they should have a:

  • [Property visible] = “Logged in” statement (this makes them invisible for users).
  • [Property order] in the range of 9000 - 9099 (this puts them at the end of the page).
