I have not used but I've seen it demoed. You need to turn on Preferences > Type > Smart Text Reflow, and choose the settings in that section. You can get it to work with non-Primary Text Frames and check Delete Empty Pages so they will be deleted if necessary as the conditions change.
I can get some pages to disappear but when showing the conditional text again the pages do not come back. The page that stayed in place has the text frame refilled but there is now overset set.
Since it's a pretty unknown workflow, it's likely there are some bugs there, unfortunately.
Wonder if Adobe is planning on bringing this feature in from FM since it makes managing book versions a snap.
Make a feature request. There aren't many Framemaker users here.
Am new to the forum world, where should I put in a feature request?
I am trying to use conditional text in InDesign the way it is used in FrameMaker. To hide pages and have the pages reflow. Conditional text seems to only adjust the text content but has no impact on the page layout in the document. Any advise will be greatly appreciated.
FrameMaker's conditional text feature hides selected text and whatever anchored objects are in the selection, like anchored frames, text insets, and tables. FrameMaker doesn't hide pages.
Typically, FrameMaker documents are a single text flow, where all the body page content is in connected text frames that flow through the document from beginning to end. Repeating headers and footers and other background content that appears to be on body pages, is really on master pages that show through on the body pages.
InDesign can work like FrameMaker, but it's not the most common or well-known way of working, because InDesign began and remains mainly a layout and design tool. (FrameMaker can be used as a layout and design tool, but that's not is most common or well-known way of working.)
When FrameMaker conditional text is hidden, the text flow contracts into the connected frames. If the delete empty pages option is enabled, empty pages at the end of the documents seem to disappear; the exception is that body pages which use master pages other than the default Left and Right, remain, even if they're blank.
in InDesign documents whose text frames on body pages are connected like FrameMaker text frames (ID calls this threaded frames,) hiding conditional text in a text flow (ID's term for flow is "story) contracts the text like FrameMaker does, and if delete empty pages is enabled, pages that use the default Left and Right master pages seem to disappear, again, like FM, from the end of the story.
You'll need to read up on and practice working with ID text frame threading. flowing text, auto-flowing text, master text frames, Smart Text Reflow, and primary text frames. Search Google for terms that include those phrases, with "InDesign" included; don't use quotation marks. Try searches with and without "tutorial" included also (without quote marks.)
If youre just new to ID, whether you're strong in FrameMaker skills or not, learning to emulate familiar FrameMaker behaviors of this kind will take some effort. As you try stuff and get stuck, send questions to this forum, with screen shots that show what you're doing, and explain what you've tried and how it's succeeded or failed to achieve your goals. It helps in screenshots to turn on hidden characters (Type > Show Hidden Characters,) show frame edges, and show text threads (View > Extras > Show Frame Edges, and View > Extras, Show Text Threads.) Some commands don't appear in menus unless the associated tool is selected, and also unless the tool is in an area that recognizes it; for example, the Text tool (text cursor) should be in text or a text frame should be selected.
Be patient. Practice a lot. You'll get it.
