i need to add a custom submenu for a module (linking to a certain page in another module).

i edit the xoops_version.php file of the module and add the following commands:
$modversion['sub'][1]['name'] = _MI_SS_SUB_SMNAME0;
$modversion['sub'][1]['url'] = "http://linktootherpage";

$modversion['sub'][2]['name'] = _MI_SS_SUB_SMNAME1;
$modversion['sub'][2]['url'] = "submit.php?op=add";

however seems that the submenu link is made relative to the module directory. for example:

http://localhost/xoops/html/modules/smartsection/http://linktootherpage

can you help, what i want to achieve is by clicking on the menu i want to go to http://linktootherpage?

thanks.

Wouldn't it be better to use a menu module such as MultiMenu?
Submenu items are supposed to be in the module and therefore expected to be relative.
