Before diving in, could you clarify whether you want those sub-menus to be _limited expandable/collapsible_ (only one open at a time, not fully toggleable), or just visually grouped with indentation or divider lines?

Also, how should it behave on mobile — should the same hierarchy appear in the side menu, or be simplified as a flat list?

This is quite a tricky layout to handle with CSS. I explored a similar idea earlier here: [Group Tabs on Desktop Menu Tab Bar using CSS](https://community.glideapps.com/t/group-tabs-on-desktop-menu-tab-bar-using-css/72798/9).  
I haven’t re-tested that code recently, so some parts may need adjustment for the current Glide DOM.
