I'm not sure you can do this in Word. If this is a requirement, have you thought about using FrameMaker where you can do this.
Well, I thought of it. However, unfortunately I depend on Word because several other actors are producing content for my project and rely on word. We also plan to use a sharepoint link...
I read somewhere that it is would be possible but I have found no indication how.
If I cannot use that would mean I cannot apply conditional tags on topic content do you agree to that?
I've just found a reference to the following methods for applying conditional text in Word:
* Styles with hidden text using different templates
* "includetext" fields that take content from different sub-documents
* Macro-controlled conditionals
* The IF field
I have no experience of using any of these though. I have also not tested whether these would come across into the RoboHelp output when you update the link. You'd also have the issue of training your users on how to set this up and use it. It doesn't sound like a totally straightforward end user task.
