This module wasn't working in the PHP4 environment ever since version 1.0 was released, due to typo in variable name. Finally fixed thanks to jonhattan.
This release adds a configuration option for rendering a collapsible cities list, with sections of the list defaulting to either expanded or collapsed. This option is only available when running the module on PHP 5, because it depends on parsing the XML version of the cities list, which currently requires PHP 5.
