Studio field (disabled 'Required field' option)

[serbanghita]

In Studio i'm trying to modify the field 'title' in the 'Contacts' module. When i go to edit, i see that the 'Required Field' is disabled so i cannot check that input field and save the options. (see the attached screenshot).

What custom file i have to edit to enable the field to be required?
Thanks a lot!

hi,
you have to create a file in custom vardefs of contacts module:

custom/Extension/modules/Contacts/Ext/Vardefs/<anyname>.php

here you have to write:
$dictionary["Contact"]["fields"]["<field name>"]["required"] = true;

then you have to rebuild extension & database from admin panel.
