Are you looking to update or delete multiple Client Contacts in REALM? This can be done using the Bulk Edit feature on the Contacts tab.
In the Contacts tab, click on Clients and toggle between the active, inactive and disabled contacts as required using the Layer Menu.
Choose the Bulk Edit button at the top right-hand side.
Choose the contacts to be amended by using the checkboxes.
Click the drop down next to Manage to bulk change the contacts' status, or click Delete.
Before the bulk edit will complete, you will be prompted to confirm that you wish to take the action (delete or mark as another status). Simply scroll to the bottom of the list to confirm.
