Currently I'm using MultiMenu 1.82 in combination with WiwiMod 0.86 and a block Standard Menu (like the XOOPS menu).

The mainlinks in the menu are like "modules/wiwimod/index.php?page=MyPage" and also the dynamic sublink pages are 'Wiwimod'-pages.

My menu is constructed like:

-MainLink 1
--Dynamic Sublink 1.1
--Dynamic Sublink 1.2
-MainLink 2
--Dynamic Sublink 2.1
--Dynamic Sublink 2.2

When I click on 'MainLink 1' the submenu unfolds, which is ok.
The problem is that also 'MainLink 2' opens.

When I use a mainlink that refer to a directory like 'modules/tinycontent2/' it works.

In the help is stated : 'To make the dynamic links to work, it is necessary to add ' / ' (trailing slash) at the end of links linking to directory!'.
But that is not in option in this case.

Am I doing something wrong or is it not possible?

There is nothing wrong. The fact is that if all your mainlinks are refering to the same module, all the related sublinks will open. Mainlinks directory are compared with the current page module directory. If it refers to the same module, it opens the sublinks. There is unfortunately nothing you can do against this.

Maybe you could try some other dynamic css menus?

Thanks for the feedback, makes the problem clear.

I will try one of the other templates.
