I was using an upgraded DNN:NAV menu using DDR.
Now it's no longer displayed after upgrade.
Is there a way to fix this?

My previous syntax was as follows in my skin.ascx

<dnn:NAV
runat="server"
id="dnnNAV"
providername="DDRMenuNavigationProvider"
ControlOrientation="Horizontal"
IndicateChildren="False"
IndicateChildImageRoot="/images/menu_down.gif"
IndicateChildImageSub="/images/menu_right.gif"
CSSNodeRoot="main_dnnmenu_rootitem"
CSSNodeHover="main_dnnmenu_rootitem_hover"
CSSNodeHoverRoot="main_dnnmenu_rootitem_hover"
CSSNodeSelectedRoot="main_dnnmenu_rootitem_selected"
CSSBreadCrumbRoot="main_dnnmenu_rootitem_selected"
CSSContainerSub="main_dnnmenu_submenu"
CSSNodeHoverSub="main_dnnmenu_itemhover"
CSSNodeSelectedSub="main_dnnmenu_itemselected"
CSSControl="main_dnnmenu_bar"
MouseOutHideDelay="1">
                                <CustomAttributes>
                                      <dnn:CustomAttribute Name="AnimationType" Value="Slide"/>
                                      <dnn:CustomAttribute Name="EasingType" Value="Expo"/>
                                      <dnn:CustomAttribute Name="EasingDirection" Value="Out"/>
                                      <dnn:CustomAttribute Name="AnimationLength" Value="1"/>
                                      <dnn:CustomAttribute Name="AnimationInterval" Value="1"/>
                                      <dnn:CustomAttribute Name="RenderMode" Value="Normal"/>
                                </CustomAttributes>
                        </dnn:NAV>

I've seen other posts about this with a resolution. Worth checking back trhought the forums. If I find one I'll link to it.

So reverting back to DNN Nav menu seemed to work... however, it still didn't work in an acceptable manner.  If you scroll over the menu, the Z-index must be messed up because the menu goes behind the text and the modules.   if logged in as admin, you can't even click on submenu items because it highlights the module with jquery with the floating "change me" (I think that's what it said) button.

I reverted back to 5.6.1 -- the DNN Done Right menu is nice... but not sure why it broke from an upgraded NAV menu from 5.6.1 to 6.0
