Hello! I am working on creating a left-side aligned vertical menu and I'm finding several different ways of doing it but I'm having a lot of issues with getting one that works how I need it to. Most of them are actually a bit more complicated than I want I think, but I'm still pretty new to HTML/CSS so I'm having trouble getting it to work correctly. Basically I have 4 menu headers, each with multiple sub-menu's below them. We want the sub-menu's to always be there, so there is no need for collapsing. We do not what the menu headers to be a selectable item. This is where I tend to run into problems. It should basically look like the open About Us menu in the image below, except that you would not be able to collapse it or select About Us. What is the best way to go about this? I have seen using lists, simply using divs, using buttons, but I'm unsure of which path to take.
