Hi Pawel,

You can give the default global macros from BOY preference settings, which can be set from menu CSS->Preference->CSS-Applications->Display->BOY. If you set cardno = 0 at here, I think your mainScreen will work as you wanted.

If you don't want to be bothered by Javascript, you can use rules for most of dynamic behavior needs. Please see attachment how the rule can invisble a group widget based on the selection in a combo box.

Thanks,
Xihui

Here you go. Hopefully, it gets through this time.
