OnePage Navigation - Active Indicator while scrolling with one excluded element?

Question

I want to make a scroll effect, so that the website changes the <a href="#" class="active"></a> to the right link while scrolling. (Example: http://callmenick.com/lab-demos/7-single-page-smooth-scroll/)

However I want to exclude one element, which refers to another website (Actually it is a dropdown with some external links). In the following jsfiddle the problem shows up. The point "Exclude" should just be skipped and not mentioned by the script. Is there any easy solution for that?

Check this Updated jsFiddle

If you do not want that external link then why you not remove "Exclude" link, Remove this HTML from your existing Code,

<li><a href="#exclude" class="exclude">Exclude</a>
</li>
