How to delete all records from Embedded Data

There is no prescribed way to do this, so you’d need to build a process around it. In my mind, you could do this two ways:

  1. Action orientated. Like the image i shared before, where it says purpose, provide an “Action” picklist. If the user selects delete all, the presses submit then you could delete them all
  2. Action orientated with selection. Building on the above option, if the user selects “delete”, then you could show a data reference referring to the embedded data?
    1. This could be multi-select (multiple records) to allow delete certain ones (or select all)
    2. You could also do this without a data reference, see this little known configuration Using an Embedded Data List as a Picklist Source (with combo-box)
