I add a new page and make it a sub-page in the Pages menu.
I Add the page as a subpage to the menu in Appearance/Menus.
Once I click to save this menu, the sub-page 'springs' back to the left and is a page on the top-level again.
I.o.W. I cannot create a menu with a sub-menu.
Do I do something wrong, coz the theme should be able to have at least 3-level-menus.
Thanks for your help.
