* - 'id' integer id of the entry
* - 'app' string app-name, defaults to $GLOBALS['egw_info']['flags']['currentapp']
* - 'status-widgets' array with status-values as key and widget names or array with select-options as value,
* all not set stati are displayed via a label-widget - just as text
* You can set $sel_options['status'] to translate the status-values to meaningful labels.
