Contacts – Form Settings
Go to Manage → CRM → Databases and click Contact form to define your custom contact form. If you do not set up a custom form, you will only be able to use the CRM Contacts module with these basic fields: Title, First and Last name, Account, User who created the contact and Description. We recommend for you to set up the fields that you need in your day-to-day work.
Up to version 6.20, you can set up the Contact form in Manage → CRM → Contacts.
