Hi MOH,

You can make a field invisible by giving invisible attribute. In the case of the the required field, you cannot save the record untill you enter data in that field.

You can try like this, make the field as required based on the value in the checkbox.

<field name='test_field' attrs="{'required':[('check_field', '=', True)]}"/>

Along with the above you can add the attribute to make the field invisible.

Thanks
