<p dir="auto">I want add an element to the top of the LeftNav which contains the user's picture and name, but it seems like all that I can specify are menu items. I don't see how I can have complicated content inside MenuItems from the examples.</p>
<p dir="auto">Any guidance of what I should do?</p>
<p dir="auto">Is there a way to make the LeftNav component composable? I need to add a custom component into the LeftNav. Is there a way to add another MenuItemType or pass in children into the render function on the LeftNav?</p>
