My client has asked me to make a sidebar on his gravity forms page similar to the one on this page (select Domestic and then select any Cleaning Service and the sidebar will appear).
I’m guessing that it’s a conditional HTML element, but I’m not sure how to add it as a sidebar, or if it’s done using an add on, or through CSS. I’ve looked all over the Internet but I can’t find anything that can help so I hope you guys can figure it out. Any hints and advice are most appreciated.
Thanks in advance!
