Hii,

Make sure CRM is installed

Go to Apps > CRM → ensure it's installed.

Set the form model to crm.lead

Edit your website form (Website → Forms), and under “Model”, select:

crm.lead (Lead / Opportunity)

Add required fields

Add at least:

• name (Lead title)
• contact_name
• email_from or phone

Odoo hides the opportunity option if essential CRM fields are missing.

Set the action to “Create an Opportunity”

If still missing:

• Go to Website > Forms > Your Form
• Under the “Action” section:
  • Choose “Create an opportunity”

If the option is still not there, check that the form's model_id is crm.lead.

Hello. Select Button. In Action select More Models and then add it to you list.
