Hello , I have been trying to make changes in the property of the selection field values. Like I have 2 fields , 1st is many 2one and other is selection field having 3 values. Now my requirement is that when I set a value in the many2one field, the 2 values in the selection field disappers and only 1 field remain in the selection field.

-> I tried to use invisible="1" when defining the field. But it didnot work. I need to do this.

-> Or I was thinking to use function like onchange function but the main issue is to set the property of selection field as invisible.

Please guide me to achieve this or any alternative for doing such thing. Thanks n regards
