I have applied the appropriate CSS and JS to make the sidebar widget sticky and that is working great.
The problem is that when I am all the way t the top of the site the sidebar widget (navigation menu) is responsive and changes size and when I scroll down and it becomes sticky the size and position changes.
Ideally I would like to disabled the responsiveness of the sidebar widget so that it is always the same size and in the same position.
I can provide login credentials to the site if needed as it is currently under development and has a coming soon page up.
