Field A = boolean Field B = select list from a taxonomy entity Field B = hidden, when field A is not select Field C = checked, when Field B have certain values. This is achieved with the #states When Field A = unselect and Field B has value, this value remain in the form_state Goal : unset the field value in an ajax callback. if ($form_state->getValue('field_A') === 0 ) { $form_state->unsetValue('field_B'); } IF Field B have no value field C should be unchecked. Not sure my approach is correct. Anny solution to unset the value is ok. For clearness : Field A is a boolean, wether there is a nearby train station. When a user check this. Field B appear, where they can choose out of a distance. When the distance is 0 or 250m or 500m, field C is checked, that says, trainstation nearby.
