Note: The 2 buttons in column use the p selector so both are toggled on click of either.
The JQuery script is in the Divi integration header.
The toggle() method was deprecated in jQuery version 1.8, and removed in version 1.9. Used here is an earlier version of jQuery (1.8 in the script tag), for this example to work.
Note: The 3 buttons in column use the a.[id###] selector so each are individually toggled on click. The bottom button has an ID not selected in the script so does not work. Not sure how to apply the script to multiple buttons without using a separate script with a unique ID selector for each!
