Standard choices column
Microsoft Dataverse includes over 100 standard choices that are created each time that you instantiate a new instance of a Dataverse datastore. You can add to a standard choice, but you can't delete an entry from a standard choice.
Explore and learn what standard choices are available in Dataverse by following these steps:
Sign in to the Power Apps portal.
On the left pane, select Choices.
Scroll through the list of over 100 standard choices. Select one of the standard choices and examine the default list of entries for that choice.
These standard choices are global choices that you can use when creating a choice column for a table.
