Applies to: WebFront 4
Note: In WebFront v4.0.7334 and later this has been implemented, so please make sure you are running the latest version.
The initial release of WebFront 4 does not contain equivalent functionality as the Silverlight version when it comes to form customizations. We are working on implementing this and are targeting Summer'17. Until then, all property extensions will still be accessible through the Extension tab (see picture below).
