How to find NavigationViewItem offset relative to parent NavigationView

[rcohn]

Hi -

I am trying to place an element vertically relative to a NavigationViewItem (kind of an overlay to that item) and am finding it difficult to place the element correctly relative to the item. The item has an ActualOffset member (with X,Y,Z components), but that is always zero. If it were not zero, then I could use the Y component to place the element.

Obviously, there must be a way to place elements relative to NavigationViewItems because the TeachingTip element is able to do that just fine. Is there a NavigationViewItem property or some trick that will let me place the element correctly? I have tried counting the NavigationViewItems and multiplying by an offset value and it works poorly.

Many thanks for any suggestions that can be offered.

Do you mean nesting the NavigationView Item?

...
<NavigationViewItem Content="Item 1" >
    <NavigationViewItem.MenuItems>
        <NavigationViewItem Content="Item 2 nested in Item 1" />
    </NavigationViewItem>
</NavigationViewItem>
<NavigationViewItem Content="Item 3" />
