Collapse-Pro-Matic has just been updated to version 1.0.8. This update includes three powerful callbacks that can be set in the plugin options page.
Expand Callback
Javascript callback that is fired after any element is expanded.
Collapse Callback
Javascript callback that is fired after any element is collapsed.
Expand/Collapse Callback
Javascript callback that is fired after any element is expanded or collapsed.
In addition to the new callbacks, a small bug fix has been included that deals with the find-me scrolling feature. Get Collapse-Pro-Matic version 1.0.8: it’s fresh out of the plugin oven.
