I'm laying out a text with lists and headings between them. I used the 'Text frame options' to split a page-wide text frame into two columns. Now, it so happens that one of my main headings is too wide to fit in a single column. I think line breaking the column is very ugly, so I'd prefer it if I could instruct this single line (or paragraph) to ignore the column separation and go all the way across the entire text frame. Not dissimilar from what two merged cells in a table would look like.
For now, I split my text into three separate frames on that page, with one of them containing the heading not split into any columns. This works, but feels like a huge hack and is very impractical in any case the text needs to reflow.
Is it possible to do this in any 'official', proper way?
