The version of Odoo Studio that is available with the Online Edition of Odoo is not the same as the version that is available with the Enterprise Edition of Odoo.

The Online Edition is ahead of the Enterprise Edition - because it is updated more frequently.

Hi,

Consider you created an app through odoo Studio -> My App

My App->studio mode->views->Form

    1.Select any field (eg: name)

    2.Click <More Parameters>.

    3.Create your input field for the model.

To add this field into your Form :

    1. Click any '+' sign appears under every field in the form view

    2. Select the field you created from the list of fields.

Now you can see your Input field in the model. I hope this helps.
