# Kupu Configuration

Link options
Link using UIDs
Links to objects on this site created by Kupu can use unique object ids so that the links remain valid even if the target object is renamed or moved elsewhere on the site. A portal transform to hide the UIDs from client browsers is currently operating for the fields:

Captioning
Allow captioned images
Images which are linked using UID based links may be automatically captioned.
Fields which appear to currently support image captioning:

Fields which use kupu but do not support image captioning:

Reference Browser
Use Kupu Reference Browser
Replace ATReferenceBrowser widget with a widget which uses Kupu's drawers instead of a popup window.
Warn before losing changes
Install Kupu code to detect form changes
Kupu can install a handler to warn before navigating away from a page where a form (even the non-Kupu fields) has been edited. Turn this off to prevent Kupu loading its own handler.
