To be clear, I do have "Show Submenu Items" set to Yes. In another template (not Joomlart) it shows in what I'm learning is called "tree" mode. But in JA_Landscape it doesn't show the submenu items until the parent menu item is clicked on. I want a vertical menu that looks like this
Main item
Subordinate item
Another Subordinate item
Another Main item
Subordinate item to another main item
etc.
