Hello, 
I'm using odoo 16. I have a task to develop a wizard where i have to show dynamic fields. Means I have a template_ids field. the template_ids field is Many2one field. 
and in the template_ids model there is another One2many field variables_id . 

In the wizard when i select template_ids then i have to check how many variables_id is available. If there is 3 variable then i have to show 3 field in the wizard . these fields are dynamic depends on variables_id. 

How to do this kind of task ? Is anyone have any idea please share
