Do you no longer need to use a custom field? Or maybe you need to use the field for something else?
NOTE: Before deleting a custom field we always recommend creating an overview of the entity, where the field is located to ensure that you do not lose valuable data.
Go to Configurations and then Custom fields:
In the drop-down list on the field you would like to delete, select the first option ***Not used***. After this has been selected you can click Save at the top and all configuration of the field will be removed.
To delete the data that was in the field you need to scroll to the top of the page and write Delete, Remember to click Save after you have written Delete.
Now you are ready to reuse the field and configure it from scratch.
