Show Dropdown made in CCTM in frontend

With 0.9.7.1 (see the dev branch), you can create entire forms on the front-end: https://code.google.com/p/wordpress-custom-content-type-manager/issues/detail?id=132

If you want to create just a single dropdown, that would take some custom development — I’d recommend that you review the source code to see how it draws its forms. In particular the includes/StandardizedCustomFields.php class and also the CCTM.php’s cctm_post_form function.

E.g. study this:

$FieldObj = CCTM::load_object('text','fields');
$post_title_def = array(
	'label' => 'My Field',
	'name' => 'my_field',
	'default_value' => ''
	'extra' => '',
	'class' => '',
	'description' => '',
	'validator' => '',
	'output_filter' => '',
	'type' => 'text'
);
$FieldObj->set_props($def);

print $FieldObj->get_create_field_instance();

Each type of field has its own properties you’d have to set and pass as arguments to the set_props() function — see the Dropdown PHP class inside of the fields folder.
