Single and dual columns on a single page?
I am using Framemaker 11 (Windows) and have not yet figured out if the following task is possible. What I am looking to do is simple in Microsoft Word, but I can't find a way to do the same in Framemaker.
Task:
I am using a single column layout to start a chapter of a book with, but at some point, I need to switch to a two column layout. However, the point at which I will make the change from 1 to 2 columns will not be at a page break. The change will occur mid-page or somewhere other than a page break. I need a way to have both column formats exist on a single page, but at the same time, allow me to add text to the single column section should I need to come back and add a paragraph or a new sentence to the single column section. IOW, the dual column section should dynamically move as the single column section expands.
I've created a video in MS Word to show what I'm looking to do: https://www.youtube.com/watch?v=iQK84TWurxo
I can create a new master page layout, yes, but the single and dual column layouts are inflexible when I do this, meaning, I cannot add additional text to the single column section without changing the text frames on the master page.
I've searched YouTube but can't find any tutorial examples.
