I'm using DNN 7.4.0 and current page structure is below:

ROOT LEVEL:

1) Home, Blog, Contact

SUBPAGES:

FOR HOME: Services, About Us, Get a Quote

FOR BLOG: Archives, Search

CONTACT: No subpages.

Some of the subpages also have children and grandchildren.

For instance:

Home > Services > Solutions > Highlights > Project Development

Entire DNN site has a lot of pages, children, grand children and great grand children.

My goal is to display only following pages on sidebar (left menu).

Level 1: Grand Parent page of current page, 

Level 2: Parent of current page and its siblings.

Level 3 :Current page and siblings of current page

I've placed a DDR Menu instance at sidebarpane at my skin and now trying to find correct nodeselector.

My ULTokens.txt file contains following:

<nav>

<ul>

[*>NODE]

</ul>

</nav>

[>NODE]

<li>

<a href="[?ENABLED][=URL][?ELSE]#[/?]">[=TEXT]</a>

[?NODE]

<ul>

[*>NODE]

</ul>

[/?]

</li>

[/>]

I have tried several nodeselectors but couldn't get to find solution yet. Could you please recommend a node selector and ultokens.txt file if my approach is incorrect?
