jquery sticky What using another jquery.sticky is possible?

[JNdev]

I have been deadlocked with jquery.sticky.js for stick sidebar, because covered the footer or all down element.

How to prevent sticky element to scroll down until it reaches the footer?
I would like to limit it to the container or row .

 

I'm not really expert with jquery

    var height = $('#footer').height();
    $("#sticker").sticky('update');

 

If can, i recommen use sticky plugin from theia Sticky or http://leafo.net/sticky-kit/ , because from leafo have complete option.
