Dynamic layout applications in VSys Live support having fields that become show or hide themselves based on the values in other fields. Changing the value of one field in an application can result in other fields changing whether or not they become visible. The rules for these are actually built in a mini programming language, and as such can do more than just "Show A if B is checked", such as "Show A if (B or C are checked) or ((Gender is male) and (Name is 'Archer'))".
Like application processing rules, which these can use a well, this is a very powerful mechanism, takes a lot of experience to configure. The setup and management of this isn't documented here, and require special assistance from the VSys Live implementation team to enable.
See Advanced VSys Live features for information on the help needed to configure these for you.
