This popup technology will work both in the CHM viewer and in all current browsers and should not cause problems with popup blockers. In addition to being blocker-transparent the popups are also activated by the user, which is explicitly permitted by most blockers.
1.In the Project Explorer select Configuration > Publishing Options > HTML Help/WebHelp > HTML Export Options. WebHelp and HTML Help have separate settings. The JS popup options for WebHelp are also used by EWriter eBooks.
3.Create your popup topic files in the Topic Files section, selecting Popup as the Topic Class. You can use all Help+Manual's formatting options, including tables, hyperlinks, formatted text, fonts, graphics, videos and animations. Just don't go overboard – if your popups are too large and contain too many features they will not be very useful!
These settings are ignored for WebHelp project popups and WebHelp field-level popups in the Premium Pack V3 Responsive skins, which use their own integrated design for the popup windows.
