Dropdown for Shop category pages?

Hello 🙂  

I am building a new site and have two menu items, both of which I'd like to have dropdowns.  The one, 'US', I do.  The other, the Shop, I cannot for the life of me figure out how to get the category pages into the dropdown folder that I was able to create.  Can anyone guide me on this?  I think I am going crazy....  Website is https://cat-manatee-zdxr.squarespace.com/

Thanks so much in advance, you'll save a girl her hair 🙂

First, you need to get Category Page URL

Next, add a Folder

Next, add a Link Item > Then you can enter Name and Category Page URL

Thanks for the reply -- I am still not able to do it, though.  I have the 'shop' menu item and it has a landing page and then three categories beneath that.  I don't want a landing page, only a dropdown menu.  It is not letting me, that I can see, create a dropdown for the shop (I can do it for other pages, just not 'store'/'shop' type pages.  I am unable to see 'add a folder' in my options in the above...could you provide more detail, specific to creating dropdown menu for 'store'/'shop' pages specifically?  I am now wondering if squarespace allows this, as I cannot find a thing about it....

Thanks!

SS changed name of some items, you can "add a Dropdown" (before its name "Folder")
