Wix Blocks Request: Trigger an Event When the Widget is Deleted
Collecting votes
Currently in Blocks, it’s not possible to listen to a "widget deleted" event.
This feature would allow you to create an event that detects when site builders who install your app delete widgets or other app parts from their site. Then, you could create an event handler and add logic to it.
We are always working to update and improve our products and your feedback is greatly appreciated.
