Hey @ninag 
I LOVEEEE this feature so much!!! I tried it and absolutely love the result!!! 
However, it only appear on the french version of the website:
I can’t see the option on the english version. 
This is what I see in the editor:
Can you please help me add this amazing feature on both version of my website? (French and english) 
My website is www.angebonbon.ca 
Love,
Audrey xx
