I have a master page with two facing pages.. each of these has a text box intended for content body. But i can only set one of these as the primary text frame. I was of the the impression we could have one per PAGE. What am i doing wrong?
here's a screenshot : Dropbox - Screenshot 2014-09-20 17.29.28.png
How about threading the two together?
Here a screenshot from my German InDesign CS6. Two different text frames for setting up a two-column text flow on every left page and a three-column text flow on the right page.
You could also use a second master where the columns and positions of the primary text frame is different and apply that to different pages of the document.
The text will flow constantly through all the pages in different numbers of columns on every page (according to the primary text frame of the applied master).
