dropdown - empty name

Use a code snippet to put html in your message!

Addressbook shows the street in that dropdown. If no street was entered, the dropdown will be empty.

Use hook_commerce_addressbook_labels_alter() to make the module use some other part of the address in the dropdown.

Quoting commerce_addressbook.api.php:

/**
 * Allows modules to alter the list of customer profile labels.
 *
 * During checkout the user selects the "address on file" from a dropdown list
 * of customer profiles. The label used to represent each customer profile
 * is the "thoroughfare" column of the addressfield. By altering the list
 * of labels, a module can use additional data to represent each customer
 * profile. Note that the list should always be keyed by customer profile id.
 *
 * @param $labels
 *   An array of labels, keyed by customer profile id.
 * @param $profiles
 *   An array of customer profile entities.

function hook_commerce_addressbook_labels_alter(&$labels, $profiles) {
  // No example.
