You can move accordions between Grid Accordion installations by exporting and then importing them. Accordions can be exported by clicking on the Export link in the Grid Accordion -> All Accordions page. The exported text is a JSON-encoded representation of the accordion's data.
To import an accordion, you need to click on the Import Accordion button in the Grid Accordion -> All Accordions page and, inside the modal window, copy the exported text.
The examples showcased on the accordion's presentation page can be found in the examples folder included in the package downloaded from CodeCanyon, and I recommend importing them into your own Grid Accordion installation to see how certain featured are used.
