Dropdown menu creation

I want to create a dropdown menu in my Omeka site and I am using Curatescape theme. I am trying to create the drop down menu with Simple Pages but it does not create the normal drop down structure. Can you please suggest me where can I start to look through in Omeka folder structure to manipulate for creating the drop down menu.
I am trying to follow Village Legacy Project this site as design. But dont know where to modify the file in omeka. For this I am trying to follow this jQuery documentation jQuery.mmenu documentation.

Appreciate you help.

Thanks in Advance

Hi @Nayeema, if you uncheck the Default Navigation box in theme settings (see screenshot below), you’ll be able to use a custom menu as configured at Admin > Appearance > Navigation.
