Looking for an update as well. Because of the Java Script limitations for WAB, I'm having to move a critical app to Experience Builder for our organization, but am now limited by the current edit widget in Experience Builder.
The 'batch edit' widget is crucial to many of our workflows and an essential part of many Web App Builder (WAB) applications currently in use. We are having to transition many of these WAB apps to Experience Builder as the WAB apps start to glitch (possibly because the underlying Classic maps glitch) but there is a glaring gap in the batch edit function. Please let us know an expected time frame to provide this OR if there are any workarounds.
