This function builds a popup menu tree of any depth from an arbitrarily deep vector of text items:

      Win.PopupTree 'One' 'Two' ('Two-1' '#Two-2') '' 'Last'
2 2

It returns a vector of the indices of the selected menus and submenus, or 0 for <Cancel>

You can flag disabled, checked or radio-selected items as for Win.Popup.
