Custom positioned anchored objects can be set "relative to spine" so they swap sides depending on the page.
Yes, that is right...
But custom frames ( "relative to spine" ) apparently does not work at all when is placed at the first line of a paragraph.
Inlines are effective...
Also, custom anchored frames does not accept inline settings: and inlines for this situation is the best as was detailed above (fast, and more and less easy production) and also for a crucial thing: the anchored heading must be inside the paragraph.
You do need to be careful about text wrap and anchor positions with custome anchored objects. Wrap only affects text after the line with the anchor.
Do you think is possible to obtain from InDesign a method to style inline anchored frames for the right page?
Or do the same with custom anchored frames but obtaining clear results instead of overlapping texts?
The second picture is devastating.
Inline, by definition, appears exactly where you anchor it. To make the custom frame work, try anchoring it in the line above. You may find you need to add an otherwise empty paragraph just to hold the anchor, and set the leading to 0, and a Keep option to keep it with the next paragraph.
For hundred of paragraphs it seems a B plan has to be accomplished.
Hum, thank you. It is interesting the solution for a minor frequency
