Hi,
I would like to add a dropdown to the header menu items with several links nested within. Please advise how this can be achieved 
Go to Online Store> Navigation> Main Menu> Add Menu Item> Drag & Drop To Place Menu Item> Save

Hope that helps!

It sia lready set up that way, but the coder who recently customised it
“deactivated” it.
