When you create a custom field, you define its title, type, and default value. You can also decide whether the field should be included in new contracts. Subsequently, you can manage and edit your custom fields.
Click "Documents" and "Contracts" in the left menu. Then click the icon with three dots (···) and select "Custom fields".
Click the icon with three dots (···), then select "Edit" to open the custom field you want to manage.
Make your changes, then click the "Save" button to finish.
More information
If the custom field is used in one or more contracts, it is not possible to change its title or type. If you want to make these changes to a custom field already used within a contract, enter the contract instead. Edit the contract and create a new custom field with the desired title, type, and default value. After that, change to the new custom field.
Select the contract that you want to change the custom fields on. Click the icon with three dots (···) and select "Edit".
Scroll down to the heading "Custom fields". Here, click the "New Custom field" button.
Create a new custom field based on the wanted values, click "Save", and then select your newly created custom field.
