You haven't said which version of RoboHelp you are using. Please always start a thread with this information.
- Please go to Help > About and include the full version number.
- If you are using 2019 also state whether it is 2019 Classic or 2019 New UI.
RoboHelp uses JavaHelp to generate the PDF output. Beyond that I am not clear what you want. Do you perhaps mean javascript?
