Footer 2 widget area has a contact form. The form on the demo is created with WP Forms, a free plugin which also has a premium version, if you need more settings. You may also use your choice of contact form plugins.
This form is also used on the Contact page.
Settings are:
- Title: Contact - Use your name.
- Select a Form: Choose Simple Contact Form (or another form you created)
- Click the Save button.
Once you have added and saved the WP Contact form, you can delete the Text widget in Footer 2 - the one that tells how to set up the form.
There is also a tutorial to remove the background-color from WPForms in Footer 2.
