@k12pieadmin That navigation bar is created using the DesignPlus tool by Cidilabs which is a software that can be purchased and added to Canvas. It uses custom JavaScript to create those elements. That particular one uses the items in a module to generate it.
If the image came from a course that is part of your institution, check with your Canvas admin on how you can gain access to the DesignPlus tool. Many institutions will probably ask you to go through some sort of training to gain access or may have limited licenses so have some sort of procedure to get access.
Hope that helps!
