The sidebar is an integral part of navigating between different sections within OPTIM. You will be able to navigate between – Open File, File Overview, Geometry, Materials, Lighting, Import Process, Element List, and Settings.
While navigating within a sub-section of a section, the option to switch to another section is faded out and disabled. This was added to prevent irregular rule creation to occur. The other sections will be available again once the sub-navigation is completed (i.e: Rule Configuration has been confirmed or cancelled)
