I have been trying to figure out a way to show certain submenus and not others using the Admin/Skins/Nav.ascx control. 

Ex of heirachy:
About (at root level - this will show up on the top menu)
--Background
--Help
-----User Guide
-----Admin Guide
--FAQs
------faq1
------faq1

If the user clicks on About from the top menu  I want to see the following on the left menu (which is all of it's children)
Background
Help
FAQs

If the user clicks on About from the top menu and then Help on the left menu, I want to see the following in the menu:
Background
Help
--User Guide
--Admin Guide
FAQs

If the user clicks on About from the top menu and then FAQs on the left menu I want to see:
Background
Help
FAQs
--faq1
--faq1

Is there a way to do this by just using the DNN menu in the skin?  Right now I have this which displays everything expanded (instead of just what is under the current selected item and the parent level of the section the user is in): So if the user clicks on FAQs it has both FAQs and Help expanded when really I just want FAQs expanded.

<dnn:NAV runat="server" id="dnnNAV2" forcedownlevel="true" level="Child" StartTabId="63" providername="DNNMenuNavigationProvider" indicatechildren="false" controlorientation="Vertical" />

Sorry if this is a basic question but I can't find a solution anywhere and I'm new to DNN.

Thanks in advance for your help!
