There is also detailed information about this in the sample projects that ship with RoboHelp 2015. Click Open on the RoboHelp Starter page and then click Samples in the ribbon on the left. See the Dynamic Content Filtering topic in Employee Care 3.
The Employee Care 3 project has been updated from the version currently shipping with RoboHelp 2015. The latest version can be downloaded from Using RoboHelp 2015 on my site. It will ship with the next RoboHelp 2015 Service Release.
The update contains important information about using Tags for filtering that is not available elsewhere.
