My issue is not exactly the same yet similar... In addition to my Header menu, I want to have a secondary menu on the side for a single page (using anchor links). Additionally, I want that side menu to have a single pulldown menu (pointing to additional anchor links).
I noticed that Squarespace support pages have exactly what I'm looking for. So I reached out to Squarespace and was told, "To do that, you would likely need to use custom code. While you’re welcome to use custom code, we aren’t able to offer troubleshooting support for advanced modifications like custom code."
Attached are a screenshot of a Squarespace support page (doing exactly what I want) and a .gif I made, showing before and after states of my desired side menu.
This seems like it should be fairly simple yet I've scoured the web and can't seem to find a straight answer:\ PULEEZE, help me! Thanks:)
