Linking system widgets
The linking system (api/js/etemplate/Et2Link/) is EGroupware’s cross-app entry-to-entry linking
mechanism - attaching a contact to an infolog entry, a file to a project, and so on. These widgets cover
searching for something to link, displaying existing links, and managing them.
See also Implementing the linking system under Tutorials for a worked example of wiring this into a new app.
