No special container ID is used because each hyperlink opener will only open the next associated container class it detects.
Unlike the general accordion function which contiguously lists each item vertically, this plugin's purpose is to let you randomly insert a hidden container anywhere on the page just because you want it exactly so. You can add multiple classes to either the opener tag or the hidden container in order to style anyway you desire.
The classes can be assigned to any element.
Thank you guys.
