This packages is created after the package from codebykyle But after an extensive refactor and updating a lot of VueJS code to the latest Laravel Nova code I made this in to a new package.
New features
[Release V2.3]
-- Fixed issue where you can't edit a listener field
-- Added Date Broadcaster field
-- Added Date Listener field
-- Added 'calculate' buttons to all visible Listener Fields
-- Added ability to turn of calculation on update forms.
[changes up to V2.2]
-- BelongsTo Broadcaster field
-- MorphTo Broadcaster field
-- Currency Listener Field
-- Hidden Listener Field
-- Code has been completely updated to latest Nova (2021-03-18)
Below pieces of the old Documentation from codebykyle I'm not really good at writing documentation. So please feel free to creat a PR for it.
