I was able to create a new menu item, with a parent of topnav. But I was not able to move another item into it, until I created a new item under it, making it a folder. Try that. You can delete the dummy menu item afterwards.
Once you've created the new menu item, you should be able to right-click on it and add children, though I haven't tried it lately.Right-clicking on reveals two choices: Update Menu, and Delete Menu Item. I don't see any way to add children. I had to go into the "modx_menus" table and manually change the parent on one other menu item to the new menu to turn the new one into a folder.
