field_to_name_array with checkbox

Hi,
i have the following code which works weel:

0 =>
array (
‘name’ => ‘dbgit_contactaccountdir_c’,
‘displayParams’ =>
array (
‘field_to_name_array’ =>
array (
‘salutation’ => ‘salutation’,
‘title’ => ‘title’,
‘department’ => ‘department’,

          ),
        ),
        'studio' => 'visible',
        'label' => 'LBL_DBGIT_CONTACTACCOUNTDIR',
      ),

I need to also to add a checkbox that becomes “CHECKED” when the data is retrieved…something like:

‘field_to_name_array’ =>
array (
‘salutation’ => ‘salutation’,
‘title’ => ‘title’,
‘department’ => ‘department’,
‘dbgit_contactaccountflag_c’ => ‘CHECKED’,

How can i accomplich this?

Thank you
