Click on Contact > Contact Forms. Here you will see the central administration panel where you can manage multiple contact forms. You will also find the Contact Form 7’s default contact form, labeled Contact Form 1.
Contact Form 1 contains all the fields a basic contact form may need. This form is ready to use and can be inserted into any page and post of your website, if you wish (this is covered further on).
Alternatively, you can create your own contact form by selecting Contact > Add New.
Creating a new contact form
Give your new contact form a name, and then scroll down to Form. Here you can edit the new contact form template.
Your template defines the various fields that will appear on your form, as well as the labels that appear next to those fields.
By default, Contact Form 7 adds a number of fields to new forms, including name, email, subject, message and send. More than likely, you will want to keep all of these fields.
