This plugin allows you to toggle the collapsible status of a panel using a pin/unpin tool. This can be specially useful in an accordion layout, where by default only one panel can be expanded at the same time (to get this working, Accordion#beforeExpand was overriden)
The included example (derived from "column.html" example) shows you the plugin in action. Extract the attached files to "examples/layout" directory, try to "pin" an expanded panel in the accordion, and then expand a different panel.
The plugin can be used in any collapsible panel, as in the panel at the center of the example (not really a useful case, just for demostration purposes).
