NestedScrollView overlapTop behavior and Toolbar

[jintoga]

Hi! I want to achieve this behavior where NestedScrollView overlap CollapsingToolbarLayout and MenuItems of Toolbar are still clickable. But the problem is if i place the NestedScrollView above SmoothAppBarLayout then the MenuItems of Toolbar are clickable but the content inside the NestedScrollView stay behind CollapsingToolbarLayout. And if i place NestedScrollView below SmoothAppBarLayout then the Toolbar stay behind NestedScrollView so its MenuItems are not clickable anymore. Any suggestion?

Toolbar's Menu Items clickable but looks bad

Toolbar's Menu Items are not click able, i want it to look like this

I already managed to resolve the problem by placing the Header inside NestedScrollView.
