Honestly, what you would like to do works just fine without the introtext, just use the description box as your introtext area. However it would be nice if the introtext placeholder worked, it doesn’t work for me either.
This might be a silly question, but does Tableau support Product Images?
Thats exactly why I wanted to use summary instead of description. A client isn’t going to hand code image information into the tiny description field. Poop.
