Hi @vlaanderen,

There are two easy ways to create menus in any sidebar. Using the "Any URL" option of the Menu link widget (http://b2evolution.net/man/menu-link-widget), as shown in the first screenshot above, and using the Free HTML widget, as suggested by @lturner here: http://forums.b2evolution.net/topic-21822 (see the second screenshot above).

Regards!

I almost forgot that there is another method, also mentioned by @lturner in the other post: creating each menu item as a "Sidebar link" post and use the Simple Sidebar Links list widget.

Thanks for your help,
I did everything as described (as I did before I posted about this), but there is just nothing appearing.
Any further advice, please?
Thank you.

Yes, it works now.
I just placed the widget in the wrong section.
Let's call this "a newbie's confusion" and put it down to learning.
Thank you for your help.
