Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

There's a discussion of this in the Application Developers Guide, section 184.108.40.206.
Summarizing: heavy flavor decays (like Bs) are generally too complex, having too many decay channels and in many cases model dependencies. For this reason Geant4 does not implement a specific decay of such particles. The most common use-case is for these decays to be handled by an event generator, like Pythia, and transfer the decay products to Geant4. An example of this is in geant4/examples/extended/eventgenerator.
