Good Day..

I have a code below for adding Add Product in More Button ...

see in more button I added this:
    
    <act_window name="Add Product"
    res_model="activity.configuration"
    src_model="activity.track"
    key2="client_action_multi"
    view_mode="form" target="new"
    view_type="form"
    id="act_new_sub_menu" />

The code above goes to configuration model where a button named action is there in header and a field named abc.. I want if I write value of field suppose i wrote def there and when I click that add button in header), a new check-box should be created (boolean field)  with same string as that of value entered in the field (def in that case)..
How can I do this?
Thanks
