Field Display Policies
----------------------

.. _20.1.1|VOSS-670|EKB-3785:

Field Display Policies are applied to certain item types in order to modify
the default form that is displayed when these items are created or accessed.

With Field Display Policies, the fields on an item detail form can be grouped,
disabled, and on-line help text can be added for a field. A field can be provided
with a new label and its position on the form can be moved up or down.

More than one Field Display Policy can apply to a particular item type so that
the selection of a particular policy will present another view of the form.

A Field Display Policy for an item type can be applied from a Menu Layout by
selecting and associating it with the item on the Menu Layout. The Menu Layout
is then selected to be part of a user Role so that users who have this role and
log in will be able to have the item displayed according to the relevant Field
Display Policy.

For example, a system may have users at Provider, Customer and Site administration
hierarchy levels - all of whom may access the same items, but perhaps some item
fields need to be hidden for administration users at a certain level. Field Display
Policies can then be made that are applied to the Menu Layout associated with
the administration users at these levels.

A quick way to add a Field Display Policy is to clone an existing Field Display
Policy, modify it as required and then to select it for the model on a user's
menu layout. In this way a user's interface can be modified from the point of user
access to the model on the menu.

There is a unique constraint on the name of the Field Display Policy per hierarchy
level. The same name can be used on another hierarchy, but a new name is needed
at the same hierarchy.

If a Field Display Policy is called ``default``, it will apply to a model by default.

.. note::

   The list view column header will also show the field title from the Field Display Policy
   if the field belongs to the list of summary attributes.
