Using Delicacy v.184.108.40.206
If I add a page as a child of a top level page, it appears on the main ribbon menu bar alongside the main top level pages.
I was expecting it to show as a drop down, or perhaps not at all.
In the code it does appear as a nested list: <ul class="children">
And I see there is a suckerfish class sf-menu
Does Delicacy support suckerfish menus?
