Is it possible to have a fixed element in the sorting alternative of Dragabble JS in a simple way?

For example in this case https://jsfiddle.net/fgbp7hku/1/

<div>
    <div>Item 0</div>
    <div class="fixed-element">Item 1</div>
    <div>Item 2</div>
</div>

I am trying to accomplish that when I try to move Item 2 to Item 0, then the result will be [Item 2, Item 1, Item 0]. However, the result is [Item 2, Item 0, Item 1].

I run through the documentation and examples for any simple switch but I was not able to find that.
