We are trying to build a specific UI template to be used in a variety of application and are finding it a bit hard to tweak the existing OS11 Side menu template. Any help to achieve the below look? We tried cloning the OS11 Side Menu, however, unable to find the right content to change. 


Can you be a bit more specific on the challenge you are facing? Is the current menu too wide and you are looking to reduce it? From your image, I can't tell what change you are looking to make.
