Fields can now have Choice Mode set to Client Side Visibility, you may wish to use this to improve performance of features that require the more basic functionality of hiding/showing fields based on choices.

Please note this does have a number of limitations:

1. The data is not secured if not visible, it is simply hidden from the markup, but can be accessed with developer tools.
2. Choice dependant choices are not supported using this method.
3. If you have two fields dependant on same choice field and one uses normal Visibility mode, then the other Client Side Visibilty, both will use Visibility mode.
4. Sections still behave as normal.
5. There maybe scenarios you come across that are not supported, if you do please revert to Visibility Mode and report issue to Sysero.
