You can use {root} options to have a try. With regard to how to use it, please check instruction here:

Hope it helps.

This may also be somewhere in the new DNNDocs website, but I didn't find it quickly.

This may be what you are looking for: NodeSelector="+0"  (I stole this from a website that, I think, does what you want.)

I find it convenient to drop the module version of the DDR Menu onto a page for experimentation.  For simplicity use the ULTokens menu and experiment with the NodeSelector parameter

I am setting up a DDR menu in 9.2 and I am only able to display either the entire menu (all visible pages) or the children of the current page. I have used Node selection expression = "RootChildren" or "CurrentChildren" but all other expressions I have tried do not work. I am trying to display all pages that are on the same level as the current page, so display all children of the current page's parent only. 

We created a (free) DDR demo skin with loads of examples.
I think you need this to show the current page's siblings:

NodeSelector="-1,0,0"

<dnn:menu menustyle="Menus/02.01-DDR-XSLT-UL-Classes" nodeselector="-1,0,0" runat="server">

Demo: https://demo.40fingers.ne...DR-Menu-NodeSelector

 

 

I just checked on a test system. Both Timo's and my suggestions work. I actually like Timo's version as it is easy to read and makes sense.

The node selector is {root},{skip},{depth}. So, in this case

-1 sets the root to the parent of the current page
0 says don't skip
0 says children of the root page

And, actually, my solution works only if the current page is a child of a top level page, so it's wrong for lower level pages!

FYI - The DDRMenu documentation has since been moved to and is maintained on the DNNDocs website. :) 

The link is 404. Where are the current docs?

Are the pages you want to display also hidden from the menu?  Meaning, when you created the page(s) - is the "display in menu" switch on?
