Instructions:
Insert a text block.
Add a link with the classname "wpex-toggle-element-trigger"
Give this link an aria-controls attribute with the value equal to the ID of the element you will open such as "#element-id" (make sure to include the pound symbol).
Add a new paragraph or multiple and wrap them in a div with the ID you set for the aria-controls attribute.
Give this new div a classname of "wpex-toggle-element"
