Goodnight,
I have a field:
tipo_ope = fields.Many2one(
'hinvoice.cat.17',
string='Tipo Ope',
readonly=True)

but I can't hide it when I select the value (25-value test) of the field type_ope. Try several options but it doesn't work.
I detail them.
<field name="campo1"  attrs="{'invisible': [('tipo_ope','=','25')]}"/>
<field name="campo2"  attrs="{'invisible': [('tipo_ope','=','25')],'required':[('tipo_ope','=','25')]}"/> 
<field name="u2" attrs="{'invisible': [('tipo_ope','=',[25])]}"/>
<field name="d2" attrs="{'invisible': [('tipo_ope','=',('value test'))]}"/>
<field name="u3" attrs="{'invisible': [('tipo_ope','=',(25))]}"/>
<field name="d3" attrs="{'invisible': [('tipo_ope','=',('25'))]}"/>
<field name="d4" attrs="{'invisible': [('tipo_ope','=',('25'))]}"/>

Thanks for your help. thanks.
