The new version of Show / Hide Content supports your needs.
The
System - Show / Hide Plugin is used for handling display in RSS, print and PDF view and rendering the whole page (so you can set them in templates, components or modules).
In RSS, print and PDF views it will render all Show / Hide Content objects open. If required, you can set the "Hide title" setting in the "
System - Show / Hide Plugin" to yes. This will hide all titles in RSS, print and PDF (so you don't have read more or things like that in those views).
To render the whole page the setting "Render whole page" must be set in the "
System - Show / Hide Plugin" to yes. If needed you can add a password (also in the system plug-in), so nobody can misuse show / hide content when the hole page is renderd. Just add password="your password set in the system plugin" to your parameters of your showhide tag, when set elsewhere than in articles.
