.htaccess hide the directory in autoindex

[Guest_imported]

when i restrict a directory with .htaccess, it also hides the directory from being seen in the parent directory. how to prevent this hidding ?

example :

let's assume there are .htaccess and .htpasswd files in this directory :

http://www.my_site.com/restricted_directory

the restricted_directory won't be displayed from this URL :

http://www.my_site.com

this URL will display a list of files (autoindex), but the restricted_directory won't be displayed. how to correct this ?
