So I found an issue, with your see it in action example live demo:
if tha navigation has a drop down and so on and so forth so:
--> child 1
-----> grand child
---> child 2
Clicking on parent bring up the drop down but does not take you to the parent page. Hover over child 1 brings up the grand child selection but clicking on it does not take you to child 1 page.
To navigate to Parent and Child 1 pages you have to right click and open in a new tab or window. Is there a way around this?
