Hi Charlesraj, For your module with

state =[
    ('draft', 'New'),
    ('cancel', 'Refused'),
    ('open', 'In Progress'),
    ('pending', 'Pending'),
    ('done', 'Hired')
 ]

You can try to use :

1.  States:
<field name="example" states="pending" />           
              ---> This field "example" is shown only when the stage is in "pending" state otherwise the field is hidden

2.  Attrs:
<field name="example" attrs="{'invisible': [('state','!=','pending')]}" />
              ---> State other than "pending" is invisible for the field "example"
