By default, in Odoo, we can create the following using the website form.

Task on Projects

Customers on Contacts

Tickets on Helpdesk

Opportunity/Lead on CRM

Apply for a Job

Send an email.

Subscribe to a newsletter.

You can also create website forms for other existing models and or new models.

To do this you will require the studio application.

Navigate to the model or model you want a form in. in this example I have a model created called “Registration”

Go to Studio -> Select Website section and press the “New Form” to create the form.

Go to the website and create a form.

The form can then be selected from the website from the list of options

Note: Some studio fields might not be visible on the website form. This is because when the studio fields are being created they will be blacklisted on the website and they will have to not be blacklisted on the website to be visible to be selected on the website.

Please review the following post for how to unblack list a studio field on the website.
