I have a feature layer in a map which includes a whole cluster (301 to be exact) of features which need deleting. Can this be done with Edit Multiple Features? If not, how should it be done?
If you have ArcGIS Pro you could add the feature service to Pro, select multiple features and then delete them using the edit tools.
@MichelleMartin15051 Edit multiple is only used to modify feature attributes for existing features of the same layer; unfortunately you cannot delete using this method. The most effective method is likely to use Pro as suggested above.
