Adding a Contact Form with Contact Form 7 Plugin
To create a contact form for your posts or pages, go to Contact > Contact Forms and then click Add New. You will see the code for a default form on the screen, with options to add additional form elements such as ‘tel’, ‘drop-down menu’, ‘checkboxes’ etc. Once you have got all the elements of your form in place, then go to the Mail tab. In the ‘To’ field, enter your own email address and also in the 'From' field.
Then give your form a name and click Save. After you save the form, a short-code for the form will appear in a blue box - you will need to copy and paste this code onto the page you want your form to appear.
