This jQuery plugin is a one-to-many linking system inspired by the pickwhip in Adobe AfterEffects.
Its purpose is to associate elements together in an easy way.
You can for instance use it in a backoffice to associate a project with categories or authors...
You can link/unlink items at will, and the association table is stored in an accessible variable.
There is also some visual options through the use of customisable classes.
Check the homepage and the source code for more info.
