I successfully experimented with such UI in Emacs where prefix menus are
represented as an outline structure in the initially collapsed state.
You can press a stylus on a top-level item, and while moving the stylus
a few pixels to the right direction it expands the submenu item under it.
Without releasing the stylus, you can move it down to the next subitem
or up to the previous item on the same level, and move the stylus again to
the right direction to expand the next subitem.  So moving the stylus left
collapses the item under the pointer, and moving the stylus right expands it.
When you arrive to the leaf item you want to execute, you can release the
stylus on it, and it executes its associated Emacs command.
