If you have UberMenu – WordPress Mega Menu installed on your site, you’ll automatically see some extra options visible when you go to duplicate your menu.

By default, both are checked, but you can disable these if you like.

Duplicate Menu Segments

If your source menu contains UberMenu Menu Segments, the Duplicator will automatically recursively duplicate all segments, and link all the copied menus up properly when you duplicate them if you enable this option.

Duplicate Widgets

If your source menu items contain any UberMenu widget areas, the Duplicator will automatically duplicate these widget areas, as well as the widgets inside them if you enable this option.

Custom Menu Item Styles

The Duplicator will automatically trigger UberMenu to re-generate any custom menu item styles for the duplicated menu – this is important for individual menu item custom styles as the items in the new menus will have new IDs.

Please note that any hand-coded custom styles will need to be copied manually and their IDs updated. (A better solution may be to use custom CSS classes that you can then re-use across menus and maintain just a single style).
