1. Paste the following code into SETTINGS → ADVANCED → CUSTOM CODE → FOOTER CODE
2. Make sure to change the buttonShowText and buttonHideText variables. That's what the button will display.
3. Make sure to change sectionTitle to the TITLE of the section itself - this is how the code knows which section to hide... In this example, I'd change it to "This is my hidden section XYZ!" (You'll see why in a minute...)
If you don't set sectionTitle correctly, this code WILL NOT WORK.
