An accordion gallery is a type of menu that displays a list of headers stacked on top of one another. When clicked on, these headers will either reveal or hide associated content. You can review an accordion gallery by clicking the accordion gallery icon in the Media and Collateral drop down. Navigate to the button on the upper left hand corner to add a new accordion gallery.
Enter your accordion gallery information like the "Title", "Description", and associate it with a page or show using the "Associated with" field in the Information tab.
In the "Elements" tab you can view all the headers and their descriptions and also add more using the "ADD" button in the upper left corner.
Enter the header in the "Name" field, enter the "Description" , the "Order" of this element, make it "Active" and Save
